AUSTIN, Texas — February 5, 2001 — System designers in need of a microcontroller with integrated current and temperature sensing capabilities can now choose the new 68HC908SR12 microcontroller, announced by Motorola’s (NYSE: MOT) Semiconductor Products Sector today. Designed for smart batteries and chargers, home appliances, security systems and other applications needing sensing capabilities, this cost-effective 8-bit microcontroller (MCU) provides on-chip current and temperature sensors, eliminating the need for additional system components and enabling reduced board size, increased reliability and low system cost. The on-chip current and temperature sensors are unusual in the industry and a first for Motorola. The 68HC908SR12 has an on-chip temperature sensor with a range of –20 to +70 degrees Celsius, a current flow sensing circuit, and a two-stage programmable amplifier. Current presence, direction and magnitude can be detected using only an external sensing resistor. By integrating these circuits on-chip, Motorola has built on its DigitalDNAä technology to simplify the end system design by allowing for small, low-power designs with a short design cycle. In addition, an enhanced electromagnetic compatibility (EMC) circuit makes customers’ system design layout work easier by reducing the need for shielding and further reducing end system cost. "In designing the new 68HC908SR12 microcontroller, Motorola’s aim was to provide a single-chip solution for original equipment manufacturers (OEMs) whose products require input from sensors for operation," said Greg White, vice president and general manager, Motorola’s Microcontroller Division. "Combined with the other features of the chip, such as embedded FLASH memory, a high-resolution analog-to-digital converter and supporting development tools and software, Motorola’s offering enables customers’ shorter design cycle times and exceptional design and manufacturing flexibility, while helping to reduce system costs." Adding to its extensive portfolio of 68HC08 MCUs with embedded FLASH technology, the 68HC908SR12 is a highly integrated chip that features in-application programming flexibility, and fast, secure write/erase capability. Motorola’s FLASH MCUs allow OEMs to program late in the manufacturing cycle and make upgrades remotely in the field, enabling the flexibility to quickly respond to the changing needs of customers and the market. 68HC908SR12 Features Motorola’s new chip includes: HC08 8-bit Core 12 Kbytes embedded FLASH 512 bytes RAM 14-channel, 10-bit analog-to-digital converter three-channel, high-speed pulse-width modulator (PWM) multiple timers multi-master I2C with system management bus (SMBus) 1.0/1.1 compatibility serial communications interface (SCI) timebase module temperature and current sensors 42-pin SDIP (shrink dual in-line package) and very small footprint 48-pin LQFP (low-profile quad flat pack) packages. Development Support Motorola offers system solutions that include chips, software libraries and example application code, development tools, comprehensive technical documentation and engineering support that is designed to make it easier for customers to design, develop, debug and accelerate products to market. Hardware development tools from Motorola include the modular evaluation system (MMEVS); a cost-effective, real-time emulator kit, including an in-circuit simulator; and the modular development system (MMDS) for high-performance, real-time emulation, including bus-state analysis. Motorola also offers its in-circuit simulator (ICS) kit for low-cost, run-time emulation. Software development tools for the 68HC08 family are available from Motorola and from a large number of independent software vendors. Price and Availability Samples and production volume of the 68HC908SR12 are available now. Suggested list price for the new chip is US $4.00 each for quantities less than 50,000 pieces. Motorola’s 68HC08 development tools are available now. Suggested list prices: emulator board (M68EML08SR12), US $495; in-Circuit simulator kit (M68ICS08SR), US $295; modular evaluation system kit (KITMMEVS08SR12), US $1,450; and modular development system kit (KITMMDS08SR12), US $3,950.
