PXAG49KBA
XA 16-bit microcontroller family 64K FLASH/2K RAM, watchdog, 2 UARTs
GENERAL DESCRIPTION
The XA-G49 is a member of Philips’ 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).
FEATURES
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
