MX10EXA Datasheet | Macronix

FEATURE - 4.5V to 5.5V - 64K bytes of on-chip Flash program memory with In System 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 Power Down.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 (e Xtended 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).
