XA 16-bit microcontroller family

32K Flash/1K RAM, watchdog, 2 UARTs

Preliminary data

XA-G39

GENERAL DESCRIPTION

The XA-G39 is a member of Philips’ 80C51 XA (eXtended

Architecture) family of high performance 16-bit single-chip

microcontrollers.

The XA-G39 contains 32 kbytes of Flash program memory, and

provides three general purpose timers/counters, a watchdog timer,

dual UARTs, and four general purpose I/O ports with programmable

output configurations.

A default serial loader program in the Boot ROM allows In-System

Programming (ISP) of the Flash memory without the need for a

loader in the Flash code. User programs may erase and reprogram

the Flash memory at will through the use of standard routines

contained in the Boot ROM (In-Application Programming).

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)

BLOCK DIAGRAM

• 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
