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).
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
