Product Summary

The PXAG49KBA is a member of Philips 80C51 XA family of high performance 16-bit single-chip microcontroller. The PXAG49KBA 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 of the PXAG49KBA 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).

Parametrics

PXAG49KBA absolute maximum ratings: (1)Operating temperature under bias: –55 to +125 ℃; (2)Storage temperature range: –65 to +150 ℃; (3)Voltage on EA/VPP pin to VSS: 0 to +13.0 V; (4)Voltage on any other pin to VSS: –0.5 to VDD+0.5V V; (5)Maximum IOL per I/O pin: 15 mA; (6)Power dissipation (based on package heat transfer limitations, not device power consumption): 1.5 W.

Features

PXAG49KBA features: (1)4.5V to 5.5V operation. For low voltage operation, consult factory.; (2)64K bytes of on-chip Flash program memory with In-System Programming capability; (3)Five Flash blocks = two 8k byte blocks and three 16k byte blocks; (4)Nearly identical to XA-G3, except for double the program and RAM memories; (5)Watchdog timer; (6)Two enhanced UARTs with independent baud rates; (7)Seven software interrupts.
