MB89P131 Datasheet | Fujitsu Semiconductor Limited

DESCRIPTION The MB89120 series is a line of single-chip microcontrollers containing a pact instruction set and a great variety of peripheral functions such as a timer, serial interface, and external interrupt. The MB89120A series is an extended variant of the MB89120, with a remote control transmission function and wake-up interrupt channels. s FEATURES - - - - - - - - - - - - - - F2MC-8L family CPU core Low-voltage operation Low current consumption (allowing for dual clock) Minimum execution time : 0.95 µs at 4.2 MHz 21-bit timebase counter I/O ports : Max. 36 ports External interrupts : 3 channels External interrupts (wake-up function) : 8 channels (only in the MB89120A series) 8-bit serial I/O : 1 channel 8-/16-bit timer/counter : 1 channel Built-in remote-control transmitting frequency generator (only in the MB89120A series) Low-power consumption modes (stop mode, sleep mode, watch mode) Package : QFP-48 CMOS technology s PACKAGE 48-pin plastic QFP (FPT-48P-M13) MB89120/120A Series s PRODUCT LINEUP Part number Item Classification MB89121 MB89123A MB89125A MB89P133A MB89P131 Mass-produced products (Mask ROM products) 4 K × 8 bits (internal mask ROM) 128 × 8 bits The number of instructions Instruction bit length Instruction length Data bit length Minimum execution time Minimum interrupt processing time Output ports (N-ch open-drain) Output ports (CMOS) I/O ports (CMOS) Total 8 K × 8 bits (internal mask ROM) One-time products ROM size 8 K × 8 bits 4 K × 8 bits (Internal PROM to (Internal PROM 16 K × 8 bits be programmed to be programmed (internal mask with a generalwith a general ROM) purpose EPROM purpose EPROM programmer) programmer) 256 × 8 bits : 136 : 8 bits : 1 to 3 bytes : 1, 8, 16 bits : 0.95 µs at 4.2 MHz : 8.57 µs at 4.2 MHz : 4 (All also serves as peripherals.) :8 : 24 (8 ports also serve as peripherals.) : 36 128 × 8 bits RAM size CPU functions Ports Timer/counter Serial I/O 8-bit timer/counter × 2 channels or 16-bit event counter × 1...
