The AT80C32X2-3CSUM is an 8-bit microcontroller based on the 80C51 core, manufactured by Microchip Technology. It operates at a maximum clock frequency of 40 MHz at 5V and 20 MHz at 3V, with an X2 speed improvement mode that doubles throughput per clock cycle. The device is ROMless, requiring external program memory, and includes 256 bytes of internal scratchpad RAM. It provides 32 programmable I/O lines, a full-duplex UART with framing error detection and automatic address recognition, three 16-bit timer/counters, and a 6-source, 4-level interrupt system. Additional features include dual data pointers, power control modes (idle, power-down, power-off flag), and a low EMI mode that inhibits ALE. The microcontroller operates over an industrial temperature range of -40°C to 85°C and requires a supply voltage of 4.5V to 5.5V. It is offered in a 40-pin PDIL (plastic dual in-line) package with through-hole mounting, suitable for prototyping and industrial applications.
The supply voltage range is 4.5V to 5.5V.
It is available in a 40-DIP (0.600", 15.24mm) package, also referred to as 40-PDIL.
The operating temperature range is -40°C to 85°C (industrial).
The part is listed as RoHS3 Compliant, but this data is unverified and should be confirmed with the manufacturer.
The maximum clock frequency is 40 MHz at 5V and 20 MHz at 3V (normal mode).
It has 256 bytes of internal RAM (256 x 8).
The device provides 32 I/O lines.
