M68000 core with a dedicated RISC CPM — what that means for your BOM
The NXP MC68302AG16VC is an integrated M68000 processor with a separate RISC Communications Processor Module (CPM) on die. The main 16-bit/8-bit core runs at 16 MHz and handles application code, while the CPM offloads serial frame processing for GCI, IDL, ISDN, NMSI, PCM, and SCPI interfaces. This dual-processor architecture means the main CPU is not stalled by bit-level protocol work — relevant if you are maintaining a legacy telecom line card or ISDN terminal adapter that needs deterministic response on the TDM bus. The part includes a DRAM controller on-chip, so external memory needs only the DRAM array itself plus address multiplex logic. No separate CPLD or FPGA for memory interface on a simple board.
Lifecycle and compliance — no LTB clock ticking
Status is Active per the manufacturer, and the part is ROHS3 compliant with no exemptions that are sunsetting. No last-time-buy notice on the horizon. For a BOM line that needs to stay qualified for another production run, this part does not force a redesign cycle.
