5V RANGE 8-BIT MCU WITH 8 TO 32K FLASH, 10-BIT ADC, 4 TIMERS, SPI, SCI INTERFACE

STMicroelectronics 

ST72324Jx ST72324Kx

1 INTRODUCTION

The ST72324 devices are members of the ST7 mi-

crocontroller family designed for the 5V operating

range.

– The 32-pin devices are designed for mid-range

applications

– The 42/44-pin devices target the same range of

applications requiring more than 24 I/O ports.

For a description of the differences between

ST72324 and ST72324B devices refer to Section

14.2 on page 152

All devices are based on a common industry-

standard 8-bit core, featuring an enhanced instruc-

tion set and are available with FLASH program

memory.

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 stand-by 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 micro-

controllers feature true bit manipulation, 8x8 un-

signed multiplication and indirect addressing

modes.
