Based on 0.5 µm CMOS technology, the µPD65881GB series offers RoHS-compliance and low power consumption, while maintaining
pin-compatible 44-pin QFP packages and 5-volt operation. All three devices are qualified to support industrial temperature
ranges of –40 to 85 degrees Celsius. These low-cost devices can be used as replacement parts in a variety of CPU-based designs
and applications such as computers, office equipment, communications equipment, and home appliances.
The new series is functionally equivalent to the previous generation of µPD7105x devices, except for some slight electrical
characteristic differences. Refer to the µPD65881GB data sheets to learn more about the differences. A sample part should be tested
in your design to ensure compatibility. Production quantities can be ordered after confirming proper operation in your product or
application environment.
The µPD65881GB devices are stocked and available through Avnet Electronics Marketing. You can expect long-term
supply and support for this upgraded series of CPU peripherals.
Product Descriptions
- The µPD65881GB-P01 programmable interval timer (PIT) delivers high-performance functionality for timing-control
applications in CPUs by incorporating a range of features, including three independently operated 16-bit counters and six
count modes for each counter.
- The µPD65881GB-P02 standard serial control unit is a programmable communication interface and features the capability
to communicate serial data via synchronous, asynchronous or bi-synchronous operation. This communications controller is compatible
with standard microcontrollers (MCUs) and features low-power standby mode and error detection for parity, overruns
- The µPD65881GB-P03 programmable peripheral interface unit suppoerts protocols ranging from basic input/output to high-level
handshakes. This chip is MCU compatible and features three 8-bit I/O ports, three programmable operation modes and no-wait
operation.
