Product details
Overview
MC68302PV25C from Motorola is a 25 MHz integrated multiprotocol processor (IMP) evaluation and development board supporting the MC68302 family, featuring 512 KB zero-wait-state SRAM, 1 MB Flash, dual RS-232 serial ports via MC68681 DUART, and logic analyzer connectors for full 68000 bus signal access - used for embedded communications protocol stack validation and industrial controller firmware development.
For engineers reviewing the MC68302PV25C datasheet, MC68302PV25C pinout, MC68302PV25C application, or MC68302PV25C equivalent, key selection considerations include IMP clock frequency (25 MHz), on-board memory configuration (SRAM/Flash/EEPROM), PCMCIA extender card compatibility, dual UART support, and expansion connector signal mapping to the MC68302 family.
Technical Context
The MC68302PV25C implements Motorola's Integrated Multiprotocol Processor architecture with an internal 68000-compatible CPU core, integrated system controller, and programmable serial interface controllers (SICs). It supports multiple communication protocols including HDLC, SDLC, and async/sync serial modes through dedicated hardware blocks.
Hardware resources include a 25 MHz crystal oscillator for the IMP section, separate +5 V DC input with onboard ±12 V generation, and expansion connectors fully mapping MC68302 address/data/control signals. The board integrates MC68681 DUART for two independent RS-232 channels with full modem control signaling.

FAQ
What is the primary function of the MC68302PV25C?
The MC68302PV25C is a complete application development system board for the MC68302 family of integrated multiprotocol processors. It provides hardware resources - including 25 MHz IMP operation, 512 KB SRAM, 1 MB Flash, dual RS-232 ports, and full bus signal access - enabling rapid firmware development, protocol stack testing, and hardware validation for embedded communications applications. The MC68302PV25C integrates both execution and debug infrastructure in a single platform.
Does the MC68302PV25C support other MC68302 variants besides the PV25C?
Yes, the MC68302PV25C board supports the full MC68302 family, including MC68LC302RC20 (20 MHz), MC68PM302RC20 (20 MHz), and MC68EN302 (with adapter). Its expansion connectors and signal routing are designed to accommodate pin-compatible variants, and the on-board monitor/debugger software is configured for multi-variant IMP initialization and register mapping. The MC68302PV25C serves as a unified hardware testbed across the family.
What debugging capabilities does the MC68302PV25C provide?
The MC68302PV25C includes an on-board IMP monitor/debugger supporting memory dump and set operations (with optional 68K instruction disassembly), single-instruction execution, software/hardware breakpoints, and application download via serial port. It interfaces with host PCs running Windows 3.0 DOS shells or SUN platforms using parallel or serial connections. The MC68302PV25C also provides logic analyzer connectors for real-time bus activity observation.
Is the MC68302PV25C compatible with PCMCIA host systems?
Yes, the MC68302PV25C includes a PCMCIA port connector with an extender card that plugs directly into standard PCMCIA sockets on host laptops or desktops. This allows direct host-to-target communication without external cables or adapters, simplifying setup for field-deployable development. The MC68302PV25C leverages this interface for debugger host communication and firmware updates.
What power supply requirements does the MC68302PV25C have?
The MC68302PV25C operates from a single +5 V DC input and includes an onboard DC-DC converter generating ±12 V for RS-232 transceivers and analog peripherals. No external negative or high-voltage supplies are needed. Power sequencing and regulation are handled internally, ensuring stable IMP core and peripheral operation. The MC68302PV25C is designed for plug-and-play use with standard bench power supplies or PC USB-powered adapters with appropriate voltage conversion.
