8-Bit OTP MCU
CSU32P10
MAIN PARAMETERS

8-bit RISC MCU with 12-bit ADC

2K×14 bits OTP ROM, 64 bytes data RAM

Introduction

The CSU32P10 is a high performance 8-bit RISC MCU with 12-bit ADC. It has 64 bytes SRAM, 1K×14 bits OTP ROM, 2 channel 32MHz 12 bit PWM, 1 channel complementary PWM, low power consumption, simple peripheral circuit. It has an excellent ADC with internal reference voltages of 1.4V / 2.0V / 3.0V / 4.0V / VDD and external input reference voltage, and the internal reference voltage supports hardware calibration. CSU32P10 is suitable for multiple applications.
