CMS12560 is a multi-toaster integrated circuit with single-sided baking function. It has baking, single-sided baking (BAGEL), reheating (REHEAT), defrosting (DEFROST), single-sided defrosting (BAGEL_DEFROST), and cancel (CANCEL) functions.
This document provides a complete functional overview of the CMS12560 integrated circuit, which is designed for single‑sided toasting applications. It describes the available functions such as BAGEL, REHEAT, DEFROST, BAGEL_DEFROST and CANCEL, and explains how each key controls the heating and defrosting processes.
The manual also includes a pin diagram, pin descriptions, electrical specifications, timing relationships, and example application circuits. Designers can use the provided formulas and tables to calculate timing based on resistor and capacitor values and to select appropriate components for desired operation modes. This manual is written in Chinese.

The CMS12560 supports TOAST, BAGEL (single‑sided toast), REHEAT, DEFROST, BAGEL_DEFROST (single‑sided defrost) and CANCEL functions.
The REHEAT timing is determined by the total oscillation resistance (R) and the capacitor values, following the relationship TIME ≈ 0.7 × R × C × 32768.
Pressing the CANCEL key stops the system and releases the electromagnet, turning off the power circuit.
Pin 1 (BAGEL) is the single‑sided toast key input, and Pin 2 (REHEAT) is the reheat key input; both have internal pull‑up resistors.
