MC68340 PRODUCT INFORMATION
MOTOROLA
The primary features of the MC68340 are as follows:
High Functional Integration on a Single Piece of Silicon
CPU32—MC68020-Derived 32-Bit Central Processor Unit
— Upward Object-Code Compatible with MC68000 and MC68010
— Additional 32-Bit MC68020 Instructions and Addressing Modes
— Unique Embedded Control Instructions
— Fast Two-Clock Register Instructions—10,045 Dhrystones/Second
Two-Channel Low-Latency DMA Controller for High-Speed Memory Transfers
— Single- or Dual-Address Transfers
— 32-Bit Addresses and Counters
— 8-, 16-, and 32-Bit Data Transfers
— 50 Mbyte/Sec Sustained Transfers (12.5 Mbyte/Sec Memory-to-Memory)
Two-Channel Universal Synchronous/Asynchronous Receiver/Transmitter (USART)
— Baud Rate Generators
— Modem Control
— MC68681/MC2681 Compatible
— 9.8 Mbits/Sec Maximum Transfer Rate
Two Independent Counter/Timers
— 16-Bit Counter
— Up to 8-Bit Prescaler
— Multimode Operation
— 80-ns Resolution
System Integration Module Incorporates Many Functions Typically Relegated to
External PALs, TTL, and ASIC, such as:
— System Configuration
— External Bus Interface
— System Protection
— Periodic Interrupt Timer
— Chip Select and Wait State Generation
— Interrupt Response
— Clock Generation
— Bus Arbitration
— Dynamic Bus Sizing
— IEEE 1149.1 Boundary Scan (JTAG)
— Up to 16 Discrete I/O Lines
— Power-On Reset
32 Address Lines, 16 Data Lines
Power Consumption Control
— Static HCMOS Technology Reduces Power in Normal Operation
— Low Voltage Operation at 3.3 V
±0.3 V (MC68340V only)
— Programmable Clock Generator Throttles Frequency
— Unused Peripherals Can Be Turned Off
— LPSTOP Provides an Idle State for Lowest Standby Current
0–16.78 MHz or 0–25.16 MHz Operation
144-Pin Ceramic Quad Flat Pack (CQFP) or 145-Pin Plastic Pin Grid Array (PGA)
As a low voltage part, the MC68340V can operate with a 3.3-V power supply. MC68340 is used throughout
this document to refer to both the low voltage and standard 5-V parts since both are functionally equivalent.
