ATMEL TS80C31X2 AT80C31X2 handbook
The TS80C31X2 is a high‑performance CMOS, ROM‑less 8‑bit microcontroller compatible with the 80C51 family. It offers four 8‑bit I/O ports, two 16‑bit timer/counters, 128 bytes of internal RAM, and an X2 speed‑improvement option that reduces the machine‑cycle to six clocks.
This manual describes the device’s features, pin‑out, special‑function register map, power‑mode operation (idle, power‑down, ONCE), and the X2 feature. Package options (PDIL40, PLCC44, VQFP44) and temperature ranges are also listed.

What power‑down modes are available?
The device supports an idle mode where the CPU is frozen while peripherals run, and a power‑down mode where RAM is saved and most functions stop.
What is the maximum operating frequency?
In standard mode the TS80C31X2 runs up to 40 MHz at 5 V (30 MHz at 3 V); in X2 mode it can reach 60 MHz at 5 V (40 MHz at 3 V).
