描述

Description
The 82C237 is a modified version of the 82C37A. The 82C237 is fully software and pin for pin compatible with the 82C37A but provides an additional mode for 16-bit DMA transfers, as well as enhanced speed. Each channel may be individually programmed for 8-bit or 16-bit data transfers.

特性

• Fully Compatible with Intersil 82C37A
- 82C237 May be Used in 8MHz and 12.5MHz 82C37A Sockets
• Optimized for 10MHz and 12.5MHz 80C286 Systems
• Special Mode Permits 16-Bit, Zero Wait State DMA Transfers
• High Speed Data Transfers:
- Up to 6.25MBytes/sec with 12.5MHz Clock in Normal Mode
- Up to 12.5MBytes/sec with 12.5MHz Clock in 16-Bit Mode
• Compatible with the NMOS 8237A
• Four Independent Maskable Channels with Autoinitialization Capability
• Cascadable to any Number of Channels
• Memory-to-Memory Transfers
• Static CMOS Design Permits Low Power Operation
- ICCSB = 10µA Maximum
- ICCOP = 2mA/MHz Maximum
• Fully TTL/CMOS Compatible
• Internal Registers may be Read from Software
