MC68302CRC20C

MC68302CRC20C refers to a variant of the MC68302 microcontroller (Motorola/Freescale). The MC68302 is a 68000‑family MCU used in embedded automotive/industrial applications, combining a 68000‑class CPU with on‑chip peripherals and flexible memory options.
Key points:
- CPU: 68000‑compatible core with a 32‑bit address space and 16‑bit data path; supports multiple privilege levels.
- Peripherals: common inclusion of timers, serial interfaces, and a flexible interrupt controller with general‑purpose I/O.
- Memory: on‑chip RAM/ROM options vary by mask/revision; external memory interfaces are supported.
- Development: program in assembly or C; toolchains include popular 68K options (CodeWarrior, GCC) and debuggers.
- Package/uses: available in surface‑mount packages for embedded boards; used in automotive and industrial controllers.
Note: CRC20C is likely a packaging or revision suffix. For exact specs, refer to the MC68302 datasheet for the specific mask/revision. If you share the exact datasheet link or full part number, I can pull precise details.

20-pin ceramic DIP package (20‑pin ceramic leaded package).

- Pin count: 40 pins (typical DIP/PLCC package for MC68302CRC20C).
- Function: Motorola MC68302 microcontroller in the 6800/MC6830x family, with on-chip CPU and peripherals (two 8-bit I/O ports, timers, a serial interface, interrupt controller, and watchdog) for embedded control applications.

Manufacturer: Motorola (specifically Motorola’s semiconductor division; part number MC68302CRC20C comes from the 68k/Motorola MC6830x family).
What kind of company: Motorola is an American multinational technology company that designs and manufactures electronics and semiconductors (historically also consumer and telecom equipment). The semiconductor division later became Freescale Semiconductor (now part of NXP).

General-purpose 68000-family MCU with on-chip peripherals for real-time control. Common application areas include automotive body/engine and other automotive electronics, industrial automation and process control, motor control and robotics, instrumentation and data acquisition, consumer electronics, and communications equipment.

Direct drop-in equivalents do not exist. The MC68302CRC20C is a 68K-family MCU with on‑chip RAM/ROM and peripherals. Closest cross-references by architecture are:
- Freescale/NXP ColdFire MCUs (e.g., MCF520X, MCF523X)
- Other 68K-family parts (older MC68HC000/MC6830x/MC68450 series) if form/peripherals align
For new designs, consider ColdFire or ARM Cortex‑M MCUs with similar peripherals and I/O.
