ST7FLITE19F1M6

8位MCU单电压闪存存储器，数据EEPROM ， ADC ， 4个定时器， SPI 8-BIT MCU WITH SINGLE VOLTAGE FLASH MEMORY, DATA EEPROM, ADC, 4 TIMERS, SPI

The ST7LITE1 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 ST7LITE1 features FLASH memory with byte-by-byte In-Circuit Programming ICP and In-Application Programming IAP capability.

Under software control, the ST7LITE1 device can be placed in WAIT, SLOW, 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 13 on page 91.The devices feature an on-chip Debug Module DM to support in-circuit debugging ICD. For a description of the DM registers, refer to the ST7 ICC Protocol Reference Manual.
