ST72314J2 8-BIT MCU WITH SINGLE VOLTAGE FLASH MEMORY,ADC, 16-BIT TIMERS, SPI, SCI INTERFACES

The ST72334J/N, ST72314J/N and ST72124J devices are members of the ST7 microcontroller family. They can be grouped as follows

All devices are based on a common industry-standard 8-bit core, featuring an enhanced instruction set.

The ST72C334J/N, ST72C314J/N and ST72C124J versions feature single-voltage FLASH memory with byte-by-byte In-Situ Programming (ISP) capability.

Under software control, all devices can be placed in WAIT, SLOW, ACTIVE-HALT or HALT mode, reducing power consumption when the application is in idle or standby state.

The enhanced instruction set and addressing modes of the ST7 offer both power and flexibility to software developers, enabling the design of highly efficient and compact application code. In addition to standard 8-bit data management, all ST7 microcontrollers feature true bit manipulation, 8x8 unsigned multiplication and indirect addressing modes.

For easy reference, all parametric data are located in Section 16 on page 107
