NEC enhances CPU peripheral line

Santa Clara, Calif.—Enhancing its lineup of CPU peripherals, NEC Electronics America Inc. has introduced three ASSPs, including a universal synchronous/asynchronous receiver transmitter (USART), a programmable timer/counter and a parallel interface unit (PIU) for standard applications such as computers, office equipment, communications equipment, test and measurement equipment, and home electronic appliances.

Based on NEC Electronics' established 0.5-micron CMOS process, the uPD65881GB-P0x series of ASSPs are functionally compatible with the industry-known uPD7105x and uPD825x support chips and provide designers with an easy migration path, a stable supply source and long-term product support.

The uPD65881GB-P0x series are designed for operation at 5V and are available in a 44-pin plastic quad flat pack (QFP) package. In addition to being lead-free to meet current RoHS regulations, all three devices are qualified to support industrial temperature ranges of -40°C to 85°C.

The uPD65881GB-P01 programmable timer/counter delivers high-performance functionality for control of CPU timing by incorporating a range of features, including three independently operated 16-bit counters and six count modes for each counter.

The uPD65881GB-P02 USART is capable of synchronous, asynchronous or bisynchronous serial communication with standard microcontrollers (MCUs). Features include low-power standby mode, error detection for parity, overrun and framing and compatibility with the previous-generation uPD71051 and uPD8251 USARTs.

The uPD65881GB-P03 PIU delivers operations ranging from basic input/output up to high-level handshake protocols. The PIU is MCU-compatible and features three 8-bit I/O ports, three programmable operating modes and no-wait operation.

Pricing: Starts at $3.43 each.
Availability: The uPD65881GB-P0x devices are available now through Avnet Electronics Marketing ( Customers with appropriate applications may request free samples from Avnet. For complete details on ordering free samples, visit Avnet Electronics Marketing's “Special Offer” page at
