INTEGRATED CIRCUITS DATA SHEET XA-S3 XA 16-bit microcontroller 32 K/1 K OTP/ROM/ROMless, 8-channel 8-bit A/D, 2 low voltage (2.7 V5.5 V), I C, 2 UARTs, 16 MB address range Product specification 2013 Sep 04 Supersedes data of 2000 Dec 01NXP Semiconductors Product specification XA 16-bit microcontroller 32 K/1 K OTP/ROM/ROMless, 8-channel 8-bit A/D, low voltage (2.7 V5.5 V), XA-S3 2 I C, 2 UARTs, 16 MB address range GENERAL DESCRIPTION Three standard counter/timers with enhanced features. All timers The XA-S3 device is a member of NXP Semiconductors XA have a toggle output capability. (eXtended Architecture) family of high performance 16-bit Watchdog timer. single-chip microcontrollers. 5-channel 16-bit Programmable Counter Array (PCA). The XA-S3 device combines many powerful peripherals on one chip. With its high performance A/D converter, timers/counters, 2 I C-bus serial I/O port with byte-oriented master and slave 2 watchdog, Programmable Counter Array (PCA), I C interface, dual functions. UARTs, and multiple general purpose I/O ports, it is suited for Two enhanced UARTs with independent baud rates. general multipurpose high performance embedded control functions. Seven software interrupts. Specific features of the XA-S3 Active low reset output pin indicates all reset occurrences 2.7 V to 5.5 V operation. (external reset, watchdog reset and the RESET instruction). A 32 K bytes of on-chip EPROM/ROM program memory. reset source register allows program determination of the cause of the most recent reset. 1024 bytes of on-chip data RAM. 50 I/O pins, each with four programmable output configurations. Supports off-chip addressing up to 16 megabytes (24 address lines). A clock output reference is added to simplify external bus 30 MHz operating frequency at 2.7 V to 5.5 V V . DD interfacing. Power saving operating modes: Idle and Power-down. Wake-up High performance 8-channel 8-bit A/D converter with automatic from power-down via an external interrupt is supported. channel scan and repeated read functions. Completes a 68-pin PLCC and 80-pin PQFP packages. conversion in 4.46 microseconds at 30 MHz. Alternate operating mode allows 10-bit conversion results.
