XA-H4
Philips Semiconductors
Single-chip 16-bit microcontroller
Preliminary specification
XA-H4
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 USARTs 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
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 USARTs with 230.4 kbps capability
Eight DMA Channels
ADDITIONAL XA-H4 FEATURES (NOT AVAILABLE ON XA-H3)
Complete DRAM controller supports up to four banks of 8 MB each
Memory controller supports 16 MB in Unified Mode
Four Match Characters are supported on each USART in
Async Mode
Hardware Autobaud on all four USARTs in Async Mode
Memory controller supports 32 MB in Harvard Mode
USARTs are improved 85C30 style
Serial ports are USARTs
Synchronous capability up to 1 Mbps, and include
HDLC/SDLC support
