San Jose, Calif. ZiLOG, Inc.'s Z8 Encore! XP family of microcontrollers now comes in the small 8-pin footprint. The new device packs all the punch of the company's larger 20- and 28-pin XP family members, but uses 80 percent less space on the printed circuit board.
Based on its 20MHz eZ8 CPU core, ZiLOG's newest MCU packs up to 4Kbytes of flash memory with in-circuit programming capability, up to 1Kbyte of register RAM and up to 128Bytes of nonvolatile data storage.
Also embedded into the chip are lots of analog functionality. Included is a four channel 10-bit analog-to-digital converter, temperature sensor, analog comparator, transimpedance (current sense) amplifier, full-duplex 9-bit UART with bus transceiver and Infrared data association (IrDA)-compliant infrared encoder/decoders.
There are also two 16-bit timers with capture, compare, and PWM capability, watch-dog timer (WDT) with internal RC oscillator, from 6 to 25 I/O pins depending upon package, up to 18 interrupts with configurable priority, single pin debugger, voltage brown-out protection (VBO), Power-on reset (POR), internal precision oscillator (5MHz/32KHz), crystal oscillator with three power settings and external RC network, option.
The devices operate from 2.7 to 3.6V with 5V-tolerant inputs over 0 to +70 C standard temperature range and from -40 to +105 C for the extended temperature operating range.
As electronic design evolves, devices in application markets such as personal handheld electronics, security, home appliances, consumer electronics and games have become increasingly complex and feature-rich. Demand for products that are easy to use, power efficient and offer high levels of integration have become key requirements for design engineers as they pack more functionality onto each new chip, according to Ramesh Ramchandani, executive vice president of sales and marketing. As a result, board real estate now comes at a premium and must be utilized as fully and as intelligently as possible.
The Z8 Encore! XP 8-pin products are available now in SOIC, PDIP and MLF-S versions and will retail at $1.25 per unit in quantities of 10,000 units. Prices could fall to under $1 in much larger quantities.
Also available is an accompanying development kit, which retails for just $49 and allows for rapid application development and shorter time to market.
