San Jose, Calif. ZiLOG Inc.'s ZNEO Z16F family of flash microcontrollers, based on the company's new ZNEO 16-bit CPU core, targets specific markets such as high-end motor control and domestic security applications.
"ZNEO addresses the significant market demand for a full-featured, 16-bit solution providing up to 128KBytes flash memory and more processing power, as well as a migration option with higher code density for our existing Z8 Encore! base," said ZiLOG interim CEO Robin Abrams. "We are already working with several customers on security and high end motor control applications with ZNEO, providing a cost-competitive, single device System-on-Chip (SOC) option which, in motor control applications for example, can not only run the motor but control other functions of the product such as the display, keypad and other user interfaces, negating the need for additional MCUs and lowering overall bill of materials."
Available immediately via ZiLOG's regular network of distributors, ZNEO delivers optimized performance and efficiency with an external bus, 24-bit address and 16-bit data. The ZNEO Z16F CPU instruction set has been optimized for near single-cycle instructions yielding up to 20 MIPS at 20MHz, combined with large zero wait state internal flash, powerful math functions, 32-bit ALU supporting 8-, 16-, and 32-bit operations, embedded 32x32 multiply/64x32 divide operations, and 16-bit bus widths and external 16-bit bus.
The compiler-friendly instruction set supports multibyte push/pop framer pointer manipulation so that code generation is very compact. A rich array of peripherals and analog features make this microcontroller suitable for a large number of applications from security panels to motor control. All ZNEO devices are RoHS compliant.
The family contains up to 128 Kbytes of internal Flash program memory with 16-bit access and in-circuit programming capability; Up to 4 KB internal RAM with 16-bit access. The internal Flash memory is accessed by the CPU at 16 bits at a time, thus improving processor throughput. The internal RAM provides easy storage of data, variables and stack operations.
There is up to twelve channels 10-bit analog-to-digital converter, an integrated operational amplifier, analog comparator and internal precision oscillator. Two full-duplex 9-bit UARTS with support for LIN and IrDA. The processor operates from 0°C to +70°C standard temperature, -40°C to +105°C extended temperature and -40°C to +105°C automotive operating ranges.

ZiLOG's move into the 16-bit MCU space is an extension of the company's application-specific product strategy and extends ZiLOG's portfolio outside of pure 8-bit products. With the scheduled introduction of its 32-bit ARM-9 family in November, ZiLOG has moved from a broad range 8-bit MCU supplier to a company that offers a full complement of devices designed to meet a broad range of application-specific needs.
Software and Development Kits
The ZNEO Z16F series is supported by a comprehensive suite of development tools and software, which includes the ZNEO Series Modular Development System (MDS), USB Smart Cable for PC to ZNEO Series MDS and 5-volt DC universal power supply. Software is supplied on CD-ROM and includes ZDS II ZNEO IDE with ANSI C-complier and sample code.
Pricing for the ZNEO Z16F series ranges from $6.00 to $8.00 at 500-unit quantities depending on memory size and peripheral configuration. Product can be ordered via local ZiLOG sales offices or ZiLOG distributor. More information on ZNEO can be found at www.zilog.com.
