Detailed Description:

Features of the W65C22
  • 2 x 8-bit, bi-directional peripheral I/O Ports
  • 2 x 16-bit programmable Interval Timer/Counters
  • Synchronous Serial bi-directional peripheral I/O Port
  • Enhanced "Handshake" feature works with either 8- or 8/16-bit systems
  • Latched Input/Output Registers on both I/O Ports
  • Programmable Data Direction Registers
  • TTL compatible I/O peripheral lines
  • 1.8V(W65C22S only) - 5V Power Supply
  • Bus compatible with 14 MHz W65C02S and W65C816S
  • Compatible with the 65xx and 68xx family of microprocessors
  • Replacement for Rockwell / GTE / CMD / Synertek / MOS Technology NMOS 6522 and CMOS 65C22 VIA's
W65C22S/W65C22N Differences

  • The W65C22S is lower power, faster and direct drive outputs with no current limiting resistors on outputs ports.
  • The W65C22N is plug replacement of NMOS 6522 devices with current limiting resistors on output ports.
  • The W65C22N does not have bus holding devices on the input, IO pins.
  • The W65C22N IRQB is an open drain output that CAN be Wire-ORd, unlike the totem-pole output of the W65C22S (some customers have had to use a diode in series with the IRQB output when using the W65C22S in their systems that had Wire-ORd interrupts).

Category Options:
65xx Family of Chips

W65C02S 8-bit Microprocessor (MPU)

The W65C02S is a low power 8–bit microprocessor utilized in a vast array of products for the Automotive, Consumer, Industrial, and Medical markets. This chip features a full external data (8–bit) and address (16–bit) bus for easy integration with 8–bit peripherals and memory.

W65C816S 8/16–bit Microprocessor (MPU)

The W65C816S extends the 65xx technology family to handle 16–bit processing with a 16MB memory space while its emulation mode allows complete hardware and software compatibility with 64KB 6502 designs. The New Direct Register and stack relative addressing provides capability for re–entrant, re–cursive and re–locatable programming.

W65C134S 8–bit Microcontroller (MCU)

The W65C134S is a feature rich 8–bit microcontroller based on the W65C02 with an advanced (originally designed for life support) Serial Interface Bus (SIB) token passing local area network for multi–W65C134S processor systems. The W65C134S has a full external memory bus (8–bit data and 16–bit address bus) for flexible system design. This MCU has an embedded debug monitor ROM with a library of routines that can help you reduce development time.

W65C265S 8/16–bit Microcontroller (MCU)

The W65C265S is the 16–bit extension of the 65xx microcontroller family. Along with increasing the memory space to 16MB with a full external memory bus (8–bit data and 24 bit address bus) for flexible system design, the W65C265S includes 3 additional UARTs, increased GPIO, Parallel Interface Bus, twin tone generators (can perform DTMF signaling) and more. Similar to the W65C134S, the W65C265S has a built–in debug monitor ROM and libraries. A reference design with OS kernel, display, ToD, data communications and power management software is available directly from WDC to ease system development.

W65C21 Peripheral Interface Adapter (PIA)

The W65C21 Peripheral Interface Adapter (PIA), a flexible I/O device, has been used successfully with many different microprocessor families especially the 65xx, 68xx/68xxx and x86 microprocessors. Two program controlled 8–bit bi–directional (bit programmable) peripheral I/O ports allow direct interfacing between the microprocessor and selected peripheral units with manual or interrupt driven hand–shaking. The W65C21 is available in both CMOS and NMOS compatible versions

W65C22 Versatile Interface Adapter (VIA)

The W65C22S Versatile Interface Adapter (VIA) is a flexible I/O device similar to the W65C21. In addition to I/O, the W65C22 provides two programmable 16–bit Interval Timer/Counters with latches and synchronous serial interface shift register. The W65C22 is available in both CMOS and NMOS compatible versions.

W65C51S Asynchronous Communications Interface Adapter (ACIA)

The WDC CMOS W65C51S Asynchronous Communications Interface Adapter (ACIA) provides an easily implemented, program controlled interface between microprocessor based systems and serial communication data sets and modems.
