7 / 161 page ST72324 7/161 1 INTRODUCTION The ST72324K and ST72324J devices are mem- bers of the ST7 microcontroller family. They can be grouped as follows: – The 32-pin ST72324K devices are designed for mid-range applications – The 42/44-pin ST72324J devices target the same range of applications requiring more than 24 I/O ports. All devices are based on a common industry- standard 8-bit core, featuring an enhanced instruc- tion set and are available with FLASH or ROM pro- gram 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. Figure 1.
