The Cmsemicon CMS605XB user manual provides pin diagrams, features, electrical parameters, safety notes, and CONFIG settings for the 8‑bit flash MCU.
This manual describes the CMS605XB 8‑bit flash microcontroller, covering its pinout, functional features, and detailed electrical specifications. It includes DC and AC characteristics, internal RC oscillator behavior, and interference test results.
Safety and configuration guidance are provided, such as proper handling of the reset pin, watchdog timer recommendations, and CONFIG register settings for oscillator, CPU clock, power‑down, and protection options. This manual is written in Chinese.
| Operating temperature | -20 °C to 85 °C |
|---|---|
| I/O pins | 11+1 (IN) |
| PWM channels | 1 channel, 8‑bit |
| Sleep current (3 V) | <3 µA |
| Package options | DIP14/SOP14, DIP8/SOP8 |
| Internal oscillator frequency | 8 MHz |
The reset pin must not be left floating; when used as an input it requires a pull‑up resistor, and it can also be configured as an open‑drain output.
The watchdog timer (WDT) should be enabled whenever possible; if it must be disabled, do so carefully and perform thorough testing.
