描述 Description

OverviewThe XA-S3 device is a member of NXP® 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.

特性 Features

•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)

•Clock output reference is added to simplify external bus interfacing

•High performance 8-channel 8-bit A/D converter with automatic channel scan and repeated read functions:
•Completes a conversion in 4.46 microseconds at 30 MHz

•Alternate operating mode allows 10‑bit conversion results




•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

•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




•50 I/O pins, each with 4 programmable output configurations

•30 MHz operating frequency at VDD = 2.7 V to5.5 V

•Power saving operating modes:
•Idle

•Power-down




•Wake-up from power-down via an external interrupt is supported

•68-pin PLCC and 80-pin PQFP packages
