8-bit market leader introduces MC908QB8 microcontroller, integrating functionality and affordability for cost-sensitive applications
Freescale Semiconductor is expanding its 8-bit portfolio with an addition to its MC68HC08 Q family of cost-effective, full-featured microcontrollers (MCUs). The MC908QB8 is a highly integrated, feature-rich solution at a low-end price point, making it ideal for consumer electronics, industrial control and automotive systems.
The MC908QB8 strengthens Freescale's 8-bit MC68HC08 Q family by offering 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.
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). 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.
The MC68HC08 Q family of cost-effective, highly integrated 8-bit MCUs targets general purpose applications. All MCUs in the family use the enhanced M68HC08 central processing unit (CPU08) and come in a variety of modules, memory sizes and package types. More than 40 million devices have shipped since the 2002 launch of this 8-bit product family.
