XA-S3
GENERAL DESCRIPTION
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. With its high performance A/D converter, timers/counters, watchdog, Programmable Counter Array (PCA), I2C interface, dual UARTs, and multiple general purpose I/O ports, it is suited for general multipurpose high performance embedded control functions.
Three standard counter/timers with enhanced features. All timers
have a toggle output capability.
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 independ...
