INTEGRATED CIRCUITS XA-S3 XA 16-bit microcontroller 32 K/1 K OTP/ROM/ROMless, 8-channel 8-bit A/D, low voltage (2.7 V–5.5 V), I2C, 2 UARTs, 16 MB address range Preliminary specification Supersedes data of 2000 Aug 22 2000 Dec 01 Philips Semiconductors Philips Semiconductors Preliminary specification XA 16-bit microcontroller 32 K/1 K OTP/ROM/ROMless, 8-channel 8-bit A/D, low voltage (2.7 V–5.5 V), I2C, 2 UARTs, 16 MB address range 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...
