PXAS33KBA
Overview
The XA-S3 device is a member of Philips Semiconductors’ XA (eXtended Architecture) family of high performance 16-bit single-chip microcontrollers. The XA-S3 device combines many powerful peripherals on one chip.
- Watchdog timer.
- 5-channel 16-bit Programmable Counter Array (PCA).
- I2C-bus serial I/O port with byte-oriented master and slave functions. Specific features of the XA-S3
- 2.7 V to 5.5 V operation.
- 32 K bytes of on-chip EPROM/ROM program memory.
- 1024 bytes of on-chip data RAM.
- Supports off-chip addressing up to 16 megabytes (24 address lines). A clock output reference is added to simplify external bus interfacing.
- Two enhanced UARTs with independent baud rates.
- Seven software interrupts.
- Active low reset output pin indicates all reset occurrences (external reset, watchdog reset and the RESET instruction). A reset source register allows program determination of the cause of the most recent reset.
