2 DESCRIPTION
The L9813 Microcontroller Unit (MCU) is a mem-
ber 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 os-
cillator 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 addi-
tion to standard 8-bit data management, the L9813
features true bit manipulation, 8x8 unsigned multi-
plication and indirect addressing modes.
The device includes an internal oscillator, CPU,
ROM/OTP/EPROM, RAM, 5 I/O lines and the fol-
lowing on-chip peripherals: Analog-to-Digital con-
verter (ADC) with 5 multiplexed analog inputs,
industry standard synchronous SPI and asynchro-
nous SCI serial interfaces, digital Watchdog, 16-
bit Timer, 2 Input Captures and 2 Output Com-
pares.
