Motorola Expands HCS12 Microcontroller Family within the Industrial Market

High Performance at Low Voltage
The MC9S12E128 and MC9S12E64 MCUs accommodate a supply voltage of 3 volts to 5 volts over an operating temperature range of -40 to +125 degrees Celsius. This capability eliminates the need for additional voltages, regulation or power supplies in many applications, such as uninterruptible power supplies (UPS) where high performance is critical to the application.

The devices' large on-board 64 Kbytes or 128 Kbytes flash memory also is specified over the entire voltage and temperature range, as is the 25 MHz Bus speed.

The HCS12 devices are especially useful in designs requiring high-speed, digital-to-analog converters, and an analog-to-digital converter, as well as applications operating down to 3 volts.

The 3V MC9S12E128 and MC9S12E64 feature:

• 3 V to 5 V operation and extended temperature (-40 to +125 degree Celsius) operating range
• 25 MHz bus speed with 40 nanosecond minimum instruction cycle time
• 128 Kbytes/64 Kbytes third generation 0.25 micron flash
• Advanced on-chip debug module with trigger and trace for faster debug
• Extensive serial communication with three asynchronous SCIs, one synchronous SPI, I2C, and infrared (IRDA) communication enabled
• Up to 12 pulse width modulated (PWM) channels, 6 with fault protection for motor control or uninterruptible power supply (UPS) applications
• Two 8-bit digital-to-analog converters (DAC)
• One 16-channel, 10-bit analog-to-digital converter (ADC)
• Low-voltage reset/interrupt
• Up to 90 general-purpose input/output options
• Supports TCP/IP and IrDa stacks (in development)

Fast System Development
The new HCS12 devices feature a single-wire background debug mode (BDM) with an on-chip emulation, trigger and trace hardware designed to allow low-cost BDM pods or simple serial cables to replace multi-thousand-dollar development tools. Previously, these on-chip features were implemented via expensive external hardware.

"Metrowerks is supporting the enhanced HCS12 devices by offering a free service pack that addresses the specific needs of developers using the improved Motorola MCUs," said Chris Joffrain, senior product manager, 8/16 Bit Architectures, Metrowerks. "The service pack works with Metrowerks' CodeWarrior Development Studio for HCS12, Release 2.0 to offer a powerful IDE, a project manager, stationery, a simulator and data visualization tools. Available now for download from the Metrowerks Web site, the service pack is designed to dramatically boost productivity for developers working with the enhanced Motorola MCUs."

Price and Availability
The first four devices in the 3 volt HCS12 family are in production and available today. Additional 3 volt HCS12 devices are planned for introduction later in 2003. Suggested resale pricing for the first four devices in 10,000-piece quantities is:

• MC9S12E128CFU (128 KB, 80 QFP Pin Package): $8.00 (USD)
• MC9S12E128CPV (128 KB, 112 LQFP Pin Package): $8.30 (USD)
• MC9S12E64CFU (64 KB, 80 QFP Pin Package): $6.40 (USD)
• MC9S12E64CPV (64 KB, 112 LQFP Pin Package): $6.70 (USD)
