TMP88CS34/CP34 is a high-speed, high-performance 8-bit single-chip microcontroller with CPU core, ROM, RAM, input/output ports, four multi-function timer/counters, serial bus interface, on-screen display, PWM output, 8-bit AD converter, and remote control signal preprocessor.
The TMP88CS34/CP34 family are high‑speed, high‑performance 8‑bit CMOS microcontrollers that integrate a CPU core, ROM, RAM, I/O ports, multiple timers, a serial bus interface, on‑screen display, PWM output, a 12‑bit AD converter, and a remote‑control signal preprocessor on a single chip. They belong to the TLCS‑870/X series and support up to 842 basic instructions with execution times of 0.25 µs at 16 MHz.
The handbook details pin assignments for the P‑SDIP42‑600‑1.78 and P‑QFP44‑1414‑0.80D packages, provides a block diagram of the internal architecture, lists electrical and AC characteristics, and gives recommended oscillating conditions for external resonators. It also includes memory map information, interrupt sources, and power‑saving modes.
