ZiLOG, Inc., the creator of the Z80 microprocessor, today announced availability of its enhanced Z8 Encore! Flash microcontroller series with 16KB to 64KB of Flash memory. The new series features an enhanced four-mode on-chip oscillator, selectable enable/disable of VBO during Stop mode for improved power consumption, and 5V-tolerant I/O pads.
The company said it will continue support for its current Z8 Encore! Flash microcontroller and will make migration assistance available to customers who wish to upgrade and take advantage of the new features.
Featuring ZiLOG's register-to-register based architecture, the enhanced Z8 Encore! Flash microcontroller combines a 20MHz core, up to 64KB of Flash memory, up to 4KB of linear register SRAM, and an array of on-chip peripherals.
The new Z8 Encore! Flash microcontroller provides voltage brown-out (VBO) protection that can be selectively enabled or disabled during Stop mode. A new on-chip oscillator provides four different oscillator modes, including one that supports external RC networks with oscillation frequencies up to 4MHz or ceramic resonators with frequencies up to 20MHz. An enhanced 12-channel, 10-bit ADC, and 5V-tolerant I/O pads round out the offering.
The new Z8 Encore! family of devices operate at more than twice the speed and at three times faster instruction execution than ZiLOG's classic Z8 MCU, while maintaining backwards compatibility with this popular architecture. The architecture utilizes ZiLOG's proprietary register-to-register approach to create designs that are simpler to program and deliver higher throughput than competing accumulator-based approaches. The devices are designed to meet the needs of designers working on consumer and appliance applications such as motor control, security systems, home appliances, personal electronic devices, and sensors.
The new Z8 Encore! Flash MCU Development Kit (Z8F64200100KIT) features the Windows version of ZiLOG Developer Studio (ZDSII), ANSI-C Compiler and C source-level debugger, evaluation board, 64KB Z8F642 Flash device, RS-232 to ZDB cable, universal power supply, and target module interface board. The On-Chip Debugger eliminates the need for an in-circuit emulator, uses a one-wire interface, and features unlimited breakpoints.
The development kit also features the ZiLOG XTools suite of tools designed to reduce total system development time. The company is offering its Z8 Encore! Flash MCU Development Kit for $39.95.
The Z8F642 Flash microcontroller development kit (Z8F64200100KIT) is available immediately from authorized ZiLOG distributors, and engineering samples of the device in all package types are available from ZiLOG. The Z8F6421AN020SC with 64KB of Flash memory in the 44-pin LQFP package will sell for $5.06 in 1K unit quantities.
The Z8 Encore! Flash microcontroller family includes seven configurations with up to 64KB (up to 512K bits) of high-speed Flash. Features include the 20MHz eZ8 CPU core, up to 4KB of linear register SRAM, and a comprehensive suite of peripherals including an on-chip DMA controller; 12 channel, 10-bit A/D; SPI; I2C; two 9-bit UART ports with integrated Infrared Data Association (IrDA)-compliant encoder/decoders; four 16-bit counter timers, each with capture and PWM capability; and a single-pin, On-Chip Debugger.
