NXP Semiconductors MC68302CPV16VC

Overview

MC68302CPV16VC from Freescale Semiconductor is a 32-bit integrated microcontroller unit (MCU) with on-chip CPU32 core, system integration module (SIM), and communications processor module (CPM). It operates at 33 MHz, supports 16-bit external data bus width, and integrates UART, SCC, timer, and interrupt controller for embedded communications systems.

For engineers reviewing the MC68302CPV16VC datasheet, MC68302CPV16VC pinout, MC68302CPV16VC application, or MC68302CPV16VC equivalent, this page delivers verified timing parameters, package mapping, functional architecture context, and real-world use cases in industrial protocol gateways and legacy telecom edge nodes.

Technical Context

The MC68302CPV16VC implements a CPU32 core executing Motorola 68000-family instruction set with 32-bit internal architecture and 16-bit external data bus. Its System Integration Module (SIM) provides memory management, chip select logic, and interrupt arbitration, while the Communications Processor Module (CPM) offloads serial protocols including HDLC, SDLC, and UART via dual SCCs and one SMC.

Timing is synchronized to a 33 MHz input clock (EXTAL), with critical interface delays specified for AS/DS assertion (3–15 ns), DTACK response (0–65 ns), and R/W transitions (0–15 ns). The device supports zero- and multi-wait-state bus cycles, with address/data hold times validated for 16-bit peripheral interfacing under worst-case temperature and voltage conditions.

FAQ

What is the operating voltage range for MC68302CPV16VC?

The MC68302CPV16VC operates at 5 V ±10%, as specified in Freescale's MC68302UM/AD Rev. 3 datasheet Section 4.1. This 4.5 V to 5.5 V range ensures compatibility with legacy 5 V TTL logic families and simplifies power design in industrial control systems where MC68302CPV16VC is commonly deployed.

Does MC68302CPV16VC support zero-wait-state memory access?

Yes, MC68302CPV16VC supports zero-wait-state operation for fast memory and peripherals. Timing parameters such as AS assert to DS assert (8 ns min), DS width asserted (30 ns min), and DTACK response (0 ns min) confirm compatibility with high-speed SRAM and ASICs when configured with appropriate wait-state settings in the SIM registers.

How many serial communication channels does MC68302CPV16VC integrate?

The MC68302CPV16VC integrates two fully independent Synchronous Communication Controllers (SCCs) and one Serial Management Controller (SMC). Each SCC supports HDLC, SDLC, and BISYNC protocols, while the SMC handles UART/RS-232 functionality - all managed autonomously by the on-chip CPM coprocessor.

What package type is used for MC68302CPV16VC?

MC68302CPV16VC uses a 132-pin Plastic Quad Flat Pack (PQFP) package with 0.65 mm lead pitch, as documented in Freescale's MC68302 packaging specification. This surface-mount package supports standard reflow soldering and provides sufficient I/O density for 16-bit data bus, address lines, and multiple peripheral interfaces.

Is MC68302CPV16VC pin-compatible with other members of the MC68302 family?

MC68302CPV16VC shares the same 132-pin PQFP footprint and core pinout with other MC68302 variants (e.g., MC68302CPV20VC), differing only in speed grade and temperature rating. Signal assignments for AS, DS, R/W, DTACK, CLK, and peripheral interfaces remain identical across the family, enabling direct substitution within the same speed bin.
