ST7FLITE2
1 INTRODUCTION
The ST7FLITE2 is a member of the ST7 microcontroller family. All ST7 devices are based on a common industry-standard 8-bit core, featuring an enhanced instruction set. The ST7FLITE2 features FLASH memory with byte-by-byte In-Circuit Programming (ICP) and InApplication Programming (IAP) capability. Under software control, the ST7FLITE2 device can be placed in WAIT, SLOW, or HALT mode, reducing power consumption when the application is in idle or standby state. Figure 1. General Block Diagram
PLL 8MHz -> 32MHz PLL x 8 or PLL X4
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 m odes .
