8-bit flash MCUs to boost low-end embedded designs

23 October 2002 DSP, Micros & Memory

Designers of cost-sensitive embedded systems from light dimmer switches and digital keypads to windshield wiper motor controllers and washing machine controllers can benefit from an 8-bit Flash microcontroller (MCU) family newly released by Motorola. The new Nitron series - six small-profile, 68HC08-based Flash MCUs, available in 8 and 16-lead packaging - will bring these designers increased flexibility in the development and manufacturing processes, as well as reduced time-to-market and system cost, according to the company.

With the 68HC08 family, Motorola offers to customers an entire spectrum of 8-bit MCUs, from very low cost to very high performance, with a wide variety of on-chip memory and peripheral options. Customers can also access a complete development environment online at no cost, as Motorola is making available free development tools for the Nitron Flash MCUs.

The Nitron family includes six devices based on the 68HC08 architecture: the 68HC908QT1, 68HC908QT2, 68HC908QT4, 68HC908QY1, 68HC-908QY2 and 68HC908QY4. Each device features the 68HC08 central processing unit (CPU), in-application and in-circuit re-programmable Flash memory (1,5K to 4K bytes), and a number of on-chip peripherals, including a two channel 16-bit timer system with selectable capture, compare and PWM, system protection such as selectable trip point LVI (low voltage inhibit) and auto-wakeup from STOP COP (computer operating properly) and a four-channel 8-bit ADC (on the QT2/QT4/QY2/QY4 versions). Available packages include the 8-lead PDIP, 8-lead SOIC, 16-lead PDIP, 16-lead SOIC, and 16-lead TSSOP.
