XA-G39 Datasheet | NXP Semiconductors

DESCRIPTION The XA-G39 is a member of Philips’ 80C51 XA (e Xtended Architecture) family of high performance 16-bit single-chip microcontrollers. The XA-G39 contains 32 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). - Boot ROM contains low level Flash programming routines for In-Application Programming and a default serial loader using the UART - 1024 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 FEATURES - 32 kbytes of on-chip Flash program memory with In-System Programming capability - Three Flash blocks = two 8 kbyte blocks and one 16 kbyte block - Provides Flash solution for XA-G37 (OTP) designs - Single supply voltage In-System Programming (ISP) of the Flash memory (VPP = VDD, or VPP = 12 V if desired) - 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 package BLOCK DIAGRAM XA CPU Core Program Memory Bus 32 KBYTES FLASH Data Bus SFR bus UART 0 1024 BYTES STATIC RAM PORT 0 PORT 1 UART 1 TIMER 0, 1 TIMER 2 PORT 2 PORT 3 WATCHDOG TIMER SU01594 2002 Mar 13 Philips Semiconductors Preliminary data XA 16-bit microcontroller...
