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

FEATURES
• 64 kbytes of on-chip Flash program memory with In-System Programming capability
• Five Flash blocks = two 8 kbyte blocks and three 16 kbyte 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 = 12 V 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 5 V
• 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
