IGLOO nano Field Programmable Gate Array (FPGA) IC 77 768 100-TQFP

General Description

The IGLOO family of flash FPGAs, based on a 130-nm flash process, offers the lowest power FPGA, a single-chip solution,

small footprint packages, reprogrammability, and an abundance of advanced features.

The Flash*Freeze technology used in IGLOO nano devices enables entering and exiting an ultra-low power mode that

consumes nanoPower while retaining SRAM and register data. Flash*Freeze technology simplifies power management

through l/O and clock management with rapid recovery to operation mode.

The Low Power Active capability (static idle) allows for ultra-low power consumption while the IGLOO nano device is

completely functional in the system. This allows the IGLO0 nano device to control system power management based on

external inputs (e.g., scanning for keyboard stimulus) while consuming minimal power.

Nonvolatile flash technology gives lGLOO nano devices the advantage of being a secure, low power, single-chip solution

that is Instant On. The IGLOO nano device is reprogrammable and offers time-to-market benefits at an ASIC-level unit

cost.

These features enable designers to create high-density systems using existing ASIC or FPGA design flows and tools.

IGLOO nano devices offer 1 kbit of on-chip, reprogrammable, nonvolatile FlashROM storage as well as clock conditioning

circuitry based on an integrated phase-locked loop (PLL). The AGLN030 and smaller devices have no PLL or RAM support.

IGLOO nano devices have up to 250 k system gates, supported with up to 36 kbits of true dual-port SRAM and up to 71

user l/Os.

IGLOO nano devices increase the breadth of the IGLOO product line by adding new features and packages for greater

customer value in high volume consumer, portable, and battery-backed markets. Features such as smaller footprint

packages designed with two-layer PCBs in mind, power consumption measured in nanoPower, Schmitt trigger, and bus

hold (hold previous l/O state in Flash*Freeze mode) functionality make these devices ideal for deployment in applications

that require high levels of flexibility and low cost.

IGLOO Field Programmable Gate Array (FPGA) IC 97 55296 9216 144-LBGA

General Description

The IGLOO family of flash FPGAs, based on a 130-nm flash process, offers the lowest power FPGA, a single-chip solution,

small footprint packages, reprogrammability, and an abundance of advanced features.

The Flash*Freeze technology used in IGLOO devices enables entering and exiting an ultra-low power mode that

consumes as little as 5 μW while retaining SRAM and register data. Flash*Freeze technology simplifies power management

through I/O and clock management with rapid recovery to operation mode.

The Low Power Active capability (static idle) allows for ultra-low power consumption (from 12 μW) while the IGLOO device

is completely functional in the system. This allows the IGLOO device to control system power management based on

external inputs (e.g., scanning for keyboard stimulus) while consuming minimal power.

Nonvolatile flash technology gives IGLOO devices the advantage of being a secure, low power, single-chip solution that is

Instant On. IGLOO is reprogrammable and offers time-to-market benefits at an ASIC-level unit cost.

IGLOO devices offer 1 kbit of on-chip, reprogrammable, nonvolatile FlashROM storage as well as clock conditioning

circuitry based on an integrated phase-locked loop (PLL). The AGL015 and AGL030 devices have no PLL or RAM support.

IGLOO devices have up to 1 million system gates, supported with up to 144 kbits of true dual-port SRAM and up to 300

user I/Os.

M1 IGLOO devices support the high-performance, 32-bit Cortex-M1 processor developed by ARM for implementation in

FPGAs. Cortex-M1 is a soft processor that is fully implemented in the FPGA fabric. It has a three-stage pipeline that offers

a good balance between low power consumption and speed when implemented in an M1 IGLOO device. The processor

runs the ARMv6-M instruction set, has a configurable nested interrupt controller, and can be implemented with or

without the debug block. Cortex-M1 is available for free from Microsemi for use in M1 IGLOO FPGAs.

The ARM-enabled devices have ordering numbers that begin with M1AGL and do not support AES decryption.

Clock Frequency Synthesis

Deriving clocks of various frequencies from a single reference clock is known as frequency synthesis.The PLL has an input

frequency range from 1.5 to 350 MHz. This frequency is automatically divideddown to a range between 1.5 MHz and

5.5 MHz by input dividers (not shown in Figure 4-19 on page 100)between PLL macro inputs and PLL phase detector

inputs. The VCO output is capable of an outputrange from 24 to 350 MHz. With dividers before the input to the PLL core

and following the VCO outputs,the VCO output frequency can be divided to provide the final frequency range from 0.75

to 350 MHz.Using SmartGen, the dividers are automatically set to achieve the closest possible matches to thespecified

output frequencies.

Users should be cautious when selecting the desired PLL input and output frequencies and the I/O bufferstandard used

to connect to the PLL input and output clocks. Depending on the I/O standards used forthe PLL input and output clocks,

the I/O frequencies have different maximum limits. Refer to the familydatasheets for specifications of maximum I/O

frequencies for supported I/O standards. Desired PLL inputor output frequencies will not be achieved if the selected

frequencies are higher than the maximum I/Ofrequencies allowed by the selected I/O standards. Users should be careful

when selecting the I/Ostandards used for PLL input and output clocks. Performing post-layout simulation can help detect

thistype of error, which will be identified with pulse width violation errors. Users are strongly encouraged toperform

post-layout simulation to ensure the I/O standard used can provide the desired PLL input oroutput frequencies. Users can

also choose to cascade PLLs together to achieve the high frequenciesneeded for their applications. Details of cascading

PLLs are discussed in the "Cascading CCCs" sectionon page 125.

In SmartGen, the actual generated frequency (under typical operating conditions) will be displayedbeside the requested

output frequency value. This provides the ability to determine the exact frequencythat can be generated by SmartGen, in

real time. The log file generated by SmartGen is a useful tool indetermining how closely the requested clock frequencies

match the user specifications. For example,assume a user specifies 101 MHz as one of the secondary output frequencies.

If the best outputfrequency that could be achieved were 100 MHz, the log file generated by SmartGen would indicate

theactual generated frequency
