XA 16-Bit Microcontroller Family

PXAS37KBBE
製造中止

The 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.

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 controller and target 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 to 5.5 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
