NXP Semiconductors Microprocessors MC68302AG20C

The MC68302AG20C is a low-cost integrated multiprotocol processor from Quarktwin Technology Ltd., designed for applications requiring a static 68000 core. It supports both 8-bit and 16-bit M68000 family systems and features an independent direct memory access (IDMA) controller, an interrupt controller, and a programmable address mapping for dual-port RAM. The device includes three timers, four programmable chip-select lines, and a low-power mode suitable for portable applications. Packaged in a 100 TQFP, the MC68302AG20C is ideal for space-constrained designs, such as PCMCIA cards. It operates at a frequency of up to 20 MHz and is available in various temperature ranges. However, it lacks the third serial communication controller found in the original MC68302, which may limit its use in systems requiring extensive serial communication capabilities. Overall, the MC68302AG20C is suitable for low-power and height-restricted applications where the full feature set of the MC68302 is not necessary.
