Atmel TS87C52X2 Microcontroller Datasheet

The TS80C52X2 is a high-performance CMOS ROM, OTP, EPROM and ROMless versions of the 80C51 CMOS single chip 8-bit microcontroller. The TS80C52X2 retains all features of the 80C51 with extended ROM/EPROM capacity (8 Kbytes), 256 bytes of internal RAM, a 6-source, 4-level interrupt system, an on-chip oscillator and three timer/counters. In addition, the TS80C52X2 has a dual data pointer, a more versatile serial channel that facilitates multiprocessor communication (EUART) and an X2 speed improvement mechanism. The fully static design ensures higher speed in low-power conditions.

About this manual

The TS87C52X2 is an 8‑bit CMOS microcontroller compatible with the 80C52 core. It offers four 8‑bit I/O ports, three 16‑bit timer/counters, a full‑duplex enhanced UART, and a dual data pointer for multiprocessor communication. The device runs at up to 40 MHz (5 V) or 30 MHz (3 V) with an X2 speed‑improvement mode that reduces the machine‑cycle to six clocks.

The microcontroller is available in PDIL40, PLCC44, VQFP44 1.4 mm, and PQFP44 packages. It operates from 2.7 V to 5.5 V, supports commercial (0 °C to 70 °C) and industrial (‑40 °C to 85 °C) temperature ranges, and includes 8 KB of on‑chip ROM/EPROM, 256 bytes of RAM, and a 6‑source, 4‑level interrupt system.
