Freescale Semiconductor expanded its 8-bit portfolio with an addition to its MC68HC08 Q family of microcontrollers (MCUs). The MC908QB8 is a highly integrated, feature-rich solution at a low-end price point, making it ideal for consumer electronics (CE), industrial control and automotive systems, said the company.

To deliver increased on-chip integration, the MC908QB8 adds increased analog precision with a 10-bit analog-to-digital converter (ADC). Design flexibility is enabled through an enhanced serial communications interface (ESCI) and a serial peripheral interface (SPI). Meanwhile, motion control capability is achieved with the help of four programmable 16-bit timer channels.

The MC908QB8 includes Freescale's embedded flash technology that allows on-the-spot field recalibration and gives designers the ability to differentiate their products based on changes in market demand. It includes 8KB of flash memory, internal clock oscillator, four programmable 16-bit timer channels, and up to 13 bi-directional input/output (I/O) lines. Freescale added that its new MCU offers a high level of on-chip integration that includes greater analog resolution, added serial communications and increased motion control. The combination of these components on a single chip reduces the need for external system components, helping decrease overall system costs, said the company.

To help customers speed and simplify development, Freescale offers a complimentary Special Edition of its CodeWarrior development studio optimized for MC908QB8 technology. The studio is included with the MC908QB8 evaluation board and is also available for download at no charge. CodeWarrior Special Edition provides everything required to edit, compile and debug applications up to 16K in size. It also includes Processor Expert technology that expedites processor bring-up by automatically creating initialization code.

MC68HC08 Q family

The MC68HC08 Q family of cost-effective, highly integrated 8-bit MCUs targets general purpose applications. All MCUs in this family use the enhanced M68HC08 central processing unit (CPU08) and come in a variety of modules, memory sizes and package types.

Available in SOIC, TSSOP and PDIP packaging options, the MC908QB8 has a suggested resale price per unit of $1.48 in 10,000-piece quantities. Additional information on the MC908QB8 can be found at the company's website.
