GENERAL DESCRIPTION

The XA-G39 is a member of Philips’ 80C51 XA (eXtended Architecture) family of high performance 16-bit single-chip microcontrollers.

FEATURES

? 32 kbytes of on-chip Flash program memory with In-System Programming capability

? Three Flash blocks = two 8 kbyte blocks and one 16 kbyte block

? Provides Flash solution for XA-G37 (OTP) designs

? Single supply voltage In-System Programming (ISP) of the Flash memory (VPP = VDD, or VPP = 12 V if desired)

? Boot ROM contains low level Flash programming routines for In-Application Programming and a default serial loader using the UART

? 1024 bytes of on-chip data RAM

? Supports off-chip program and data addressing up to 1 megabyte (20 address lines)

? Three standard counter/timers with enhanced features (same as XA-G3 T0, T1, and T2). All timers have a toggle output capability

? Watchdog timer

? Two enhanced UARTs with independent baud rates

? Seven software interrupts

? Four 8-bit I/O ports, with 4 programmable output configurations for each pin

? 30 MHz operating frequency at 5 V

? Power saving operating modes: Idle and Power-Down. Wake-Up from power-down via an external interrupt is supported.

? 44-pin PLCC package
