Quick Detail:

XA 16-bit microcontroller family 64K FLASH/2K RAM, watchdog, 2 UARTs

Description:

The XA-G49 is a member of ’ 80C51 XA (eXtended Architecture) family of high performance 16-bit single-chip microcontrollers.

The XA-G49 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).

Applications:

• 4.5V to 5.5V operation. For low voltage operation, consult factory.

• 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

• Nearly identical to XA-G3, except for double the program and RAM memories

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

• 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 (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 5V

• Power saving operating modes: Idle and Power-Down.

Wake-Up from power-down via an external interrupt is supported.

• 44-pin PLCC and 44-pin LQFP packages
