ST72334J/N, ST72314J/N, ST72124J 8-bit MCU with single voltage FLASH memory, ADC, 16-bit timers, SPI, SCI interfaces, power supply supervisor, low consumption resonator, RC oscillators, external clock source, interrupt controller, I/O, watchdog, PWM/pulse generator, SPI, SCI, hardware/software development package.
This document is a technical datasheet for the ST72334J/N, ST72314J/N, and ST72124J microcontrollers, which are members of the ST7 family. These 8-bit devices feature single-voltage flash memory with in-situ programming capabilities, 256 bytes of EEPROM (on specific models), and 384 or 512 bytes of RAM. They include peripherals such as an 8-bit ADC, two 16-bit timers, SPI, and SCI interfaces compatible with LIN.
| Program memory | 8K or 16K bytes |
|---|---|
| Data memory (EEPROM) | 256 bytes |
| RAM | 384 or 512 bytes |
| Operating Supply | 3.2V to 5.5V |
