XA XA Microcontroller IC 16-Bit 30MHz ROMless 100-LQFP (14x14)

DESCRIPTION

The powerful 16-bit XA CPU core and rich feature set make the

XA-H3 and XA-H4 devices ideal for high-performance real-time

applications such as industrial control and networking. By supporting

of up to 32 MB of external memory, these devices provide a low-cost

solution to embedded applications of any complexity. Features like

DMA, memory controller and four advanced UARTs help solve I/O

intensive tasks with a minimum of CPU load

The XA-H3 feature set is a subset of the XA-H4 (see Table 1). The

XA-H3/H4 devices are members of the Philips XA (eXtended

Architecture) family of high performance 16-bit microcontrollers.

The XA-H3 and XA-H4 are designed to significantly minimize the

need for external components.

FEATURES

• Large Memory Support (up to 6 MB external)

• De-multiplexed Address/Data Bus

• Six Programmable Chip Selects

– Support for Unified Memory – allows easy user modification of

all code

– External ISP Flash support for easy code download

• Dynamic Bus Sizing – each of 6 Chip Selects can be programmed

for 8-bit or 16-bit bus.

• Dynamic Bus Timing – each of 6 chip selects has individual

programmable bus timing.

• 32 Programmable General Purpose I/O Pins

• Four UARTs with 230.4 kbps capability

• Eight DMA Channels
