Low voltage 8-bit microcontrollers with
UART, I2C-bus and ADC
Product specification
P80CL580; P83CL580
Access to memory addressing is as follows:
• Registers in one of the four register banks through
register, direct or register-indirect
• Lower 128 bytes of internal RAM through direct or
register-indirect; upper 128 bytes of internal RAM
through direct
• Special Function Registers through direct
• External Data Memory through register-indirect
• Program Memory look-up tables through base-register
plus index-register-indirect.
The P8xCL580 is classified as an 8-bit device since the
internal ROM, RAM, Special Function Registers,
Arithmetic Logic Unit and external data bus are all 8-bits
wide. It performs operations on bit, nibble, byte and
double-byte data types.
Facilities are available for byte transfer, logic and integer
arithmetic operations. Data transfer, logic and conditional
branch operations can be performed directly on Boolean
variables to provide excellent bit handling.
