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 64 kbytes 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
- 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
