Product Details
MEMORY ORGANIZATION PROGRAM MEMORY: Up to 4 Kbytes of the program memory can reside on-chip (except 80C31BH). In addition the device can address up to 64K of program memory external to the chip. DATA MEMORY: This microcontroller has a 128 x 8 on-chip RAM. In addition it can address up to 64 Kbytes of external data memory. The Intel 87C51/80C51BH/80C31BH is a single-chip control-oriented microcontroller which is fabricated on Intel’s reliable CHMOS III-E technology. Being a member of the MCSÉ 51 controller family, the 87C51/80C51BH/80C31BH uses the same powerful instruction set, has the same architecture, and is pin-forpin compatible with the existing MCS 51 controller family of products. ■ High Performance CHMOS EPROM ■ 24 MHz Operation ■ Improved Quick-Pulse Programming Algorithm ■ 3-Level Program Memory Lock ■ Boolean Processor ■ 128-Byte Data RAM ■ 32 Programmable I/O Lines ■ Two 16-Bit Timer/Counters ■ Extended Temperature Range (b40§C to a85§C) ■ 5 Interrupt Sources ■ Programmable Serial Port ■ TTL- and CMOS-Compatible Logic Levels ■ 64K External Program Memory Space ■ 64K External Data Memory Space ■ ONCE Mode Facilitates System Testing ■ Power Control Modes — Idle — Power Down |
