TS80C52X2 is high performance CMOS ROM, OTP, EPROM and ROMless versions of the 80C51 CMOS single chip 8-bit microcontroller.
The TS80C52X2 is an 8‑bit CMOS microcontroller compatible with the 80C52 core, offering up to 8 KB of on‑chip ROM/EPROM, 256 bytes of RAM, a dual data pointer, and a versatile serial channel for multiprocessor communication. It includes a 6‑source, 4‑level interrupt system, three 16‑bit timer/counters, and a full‑duplex enhanced UART.
The device operates from 2.7 V to 5.5 V, supports both standard and X2 speed modes (up to 40 MHz equivalent), and is available in multiple packages such as PDILAO, PLCC44, VQFP44, PQFP, CQPJ44, and CDILA0. Temperature ranges cover commercial (0 °C to 70 °C) and industrial (‑40 °C to 85 °C) environments.
