MME 80-SIO/0 Vintage Controller DIP-40

From the shop's description

MME 80-SIO/0 Vintage Controller DIP-40 The 80-SIO/0 is a powerful component for handling serial data, supporting both asynchronous and synchronous communication. This makes it a flexible solution for a range of applications, from simple terminal interfaces to more complex network protocols. It features two independent full-duplex channels, each with its own modem controls. The device can generate and check Cyclic Redundancy Codes (CRC) in synchronous modes to ensure data integrity. Features Dual-Channel Flexible Protocol Support High-Speed Operation Advanced Buffering Data Integrity Integrated Modem Controls Daisy-Chain Interrupts Versatile I/O Software Configurable Specifications Specification Value Technology N-channel silicon-gate depletion-load Power Supply Single +5V Clock Single-phase 5V Package 40-pin DIP (Dual In-line Package) I/O Compatibility TTL compatible Data Bus 8-bit bidirectional (D0-D7) Dimensions 16 x 52 x 8 mm Applications Interfacing with modems for data communication. Connecting to serial printers and terminals. Use in cassette or floppy disk interfaces. Implementation of various serial communication protocols in embedded systems. Processor-to-processor communication. Data concentrators. DataSheet 80-SIO/0
