Description
The L9813 Microcontroller Unit (MCU) is a member of the ST7 family of Microcontrollers. The device is based on an industry-standard 8-bit core and features an enhanced instruction set. The device is normally operated at an 16MHz oscillator frequency. Under software control, the L9813 may be placed in either Wait, Slow or Halt modes, thus reducing power consumption. The enhanced instruction set and addressing modes afford real programming potential. In addition to standard 8-bit data management, the L9813 features true bit manipulation, 8x8 unsigned multiplication and indirect addressing modes. The device includes an internal oscillator, CPU, ROM/OTP/EPROM, RAM, 5 I/O lines and the following on-chip peripherals: Analog-to-Digital converter (ADC) with 5 multiplexed analog inputs, industry standard synchronous SPI and asynchronous SCI serial interfaces, digital Watchdog, 16bit Timer, 2 Input Captures and 2 Output Compares.
