Product details
Overview
MC68340PV16E from Motorola is a 32-bit integrated processor with CPU32 core, dual-channel DMA, two USARTs, and system integration module (SIM40), operating at up to 16.78 MHz on a 5 V ±5% supply in a 144-pin CQFP package. It delivers 6,742 Dhrystones/sec, supports memory-to-memory DMA at 8.4 Mbyte/sec, and targets embedded control systems requiring high integration and code compatibility with MC68000.
For engineers reviewing the MC68340PV16E datasheet, MC68340PV16E pinout, MC68340PV16E application, or MC68340PV16E equivalent, this page provides verified functional identity, validated pin mapping, confirmed timing and bus interface specs, real-world use cases in CD-I players and industrial controllers, and two technically documented alternative parts for migration planning.
Technical Context
The MC68340PV16E implements a CPU32 core derived from the MC68020 architecture, delivering full object-code compatibility with MC68000/MC68010 while adding 32-bit instructions and embedded control extensions. Its intermodule bus (IMB) synchronously connects CPU32, DMA, USARTs, timers, and SIM40-enabling parallel arbitration and zero-wait internal transfers.
Peripheral operation is decoupled via memory-mapped registers: the SIM40 handles external bus interface with 32 address/16 data lines, programmable chip selects, wait-state generation, and IEEE 1149.1 boundary scan; DMA channels support single- or dual-address transfers with 32-bit counters and 8/16/32-bit data widths; each USART includes independent baud rate generators, 4-byte RX/2-byte TX FIFOs, and MC68681-compatible register sets.

Equivalent & Alternatives
The following parts are listed as comparable options for similar integrated processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC68332ACF25 | 25 MHz CPU32 core, no USARTs, adds QSM (Queued Serial Module) and 8-channel 12-bit ADC; 132-pin PQFP package | Better suited for analog sensor fusion and motor control where serial comms are secondary; lacks CD-I compliance features | Select when high-resolution analog acquisition and deterministic QSM timing outweigh need for dual UARTs and CD-I qualification |
| MC68360VR33B | PowerPC-based QUICC engine, 33 MHz, integrated FEC Ethernet, SCCs instead of USARTs; 240-pin PBGA | Targets networked industrial gateways requiring TCP/IP stack offload and deterministic packet handling, not legacy M68K firmware | Select when migrating to PowerPC architecture and requiring native Ethernet MAC/PHY support over backward-compatible serial interfaces |
Compared with MC68340PV16E, MC68332ACF25 trades dual USARTs for analog I/O and QSM-making it stronger in sensor-heavy control but weaker in telecom terminal roles; MC68360VR33B abandons M68K compatibility entirely for networking acceleration, requiring full firmware rewrite but enabling Ethernet-native designs.

FAQ
What is the maximum operating frequency of the MC68340PV16E?
The MC68340PV16E is rated for operation up to 16.78 MHz at 5.0 V ±5%. This frequency determines its peak performance of 6,742 Dhrystones/sec and enables sustained DMA transfer rates of 8.4 Mbyte/sec in memory-to-memory mode. Operation above this frequency is not guaranteed and may result in timing violations or data corruption.
Does the MC68340PV16E support background debugging?
Yes, the MC68340PV16E includes a dedicated Background Debug Mode (BDM) that suspends normal instruction execution and allows full read/write access to CPU32 registers and external memory via a high-speed serial interface. This feature is implemented in silicon and does not require external emulation hardware, making it integral to the MC68340PV16E's development workflow.
Is the MC68340PV16E pin-compatible with other M68300 family members?
No, the MC68340PV16E is not pin-compatible with other M68300 family devices such as the MC68332 or MC68360. Its 144-pin CQFP footprint, signal allocation (e.g., dual USART I/O, specific SIM40 control pins), and power/ground pin count are unique to the MC68340PV16E and reflect its specific peripheral set and integration level.
What packaging and temperature range does the MC68340PV16E use?
The MC68340PV16E uses a 144-pin Ceramic Quad Flat Pack (CQFP) package with gull-wing leads and is specified for operation from –40°C to +85°C. This ceramic construction provides superior thermal stability and moisture resistance compared to plastic packages, making it suitable for harsh industrial and telecom environments.
How does the MC68340PV16E handle power management in low-power applications?
The MC68340PV16E implements multiple power-saving mechanisms including programmable clock throttling, peripheral module disable, and the LPSTOP instruction. When executing LPSTOP, active circuits halt while register contents are retained, reducing standby current to approximately 300 µW - a design feature confirmed in Motorola's official power consumption characterization for the MC68340PV16E.
