Overview
PRELIMINARY MX10EXA XA 16-bit Microcontroller Family 64K Flash/2K RAM, Watchdog, 2UARTs FEATURE • 4.
5V to 5.
5V • 64K bytes of on-chip Flash program memory with InSystem Programming capability • Five Flash blocks = two 8k byte blocks and three 16k byte blocks • Single supply voltage In-System Programming of the Flash memory, (VPP=VDD or VPP=12V ifdesired) • Boot ROM contains low level Flash programming routines for In-Application Programming and a default serial loader using the UART • 2048 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 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 5V • Power saving operating modes: Idle and PowerDown.
Wake-Up from power-down via an external interrupt is supported.
• 44-pin PLCC (MX10EXAQC) and 44-pin LQFP (MX10EXAUC) packages GENERAL DESCRIPTION The MX10EXA is a member of Philips’ 80C51 XA (eXtended Architecture) family of high performance 16bit single-chip microcontrollers.
The MX10EXA contains 64k bytes 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).
