Freescale Semiconductor has expanded its line of 8-bit microcontroller (MCU) chips with the launching of its S08QG family of highly integrated devices.

To deliver increased on-chip integration, the company's MC9S08QG8/QG4 MCUs add an enhanced 8-channel, 10-bit analog-to-digital converter designed for better resolution, speed of conversion and low-power. The onboard analog integration allows customers to easily interface to analog inputs with minimal external glue logic. The inclusion of a serial communications interface (SCI), a serial peripheral interface (SPI) module and inter-integrated circuit (IIC) bus modules maximizes the customer's options for external components to interface with and enables increased design flexibility, according to the company.

Flexible timer options allow for greater software flexibility with the 8-bit modulo timer module (MTIM), as well as motion control capabilities with the 2-channel Timer/PWM module (TPM). "By offering tightly integrated 8-bit MCUs that combine flexibility and competitive price points, Freescale is giving designers wide latitude in choosing the right devices for their systems," said Eddie Sinnott, 8-bit MCU operations manager for Freescale. "The 9S08QG8/QG4 MCUs provide designers with the necessary functionality at a very competitive suggested resale price to enable even the most demanding and cost-sensitive application."

Based on the HCS08 core, the MC9S08QG8/QG4 runs at up to 20MHz (10MHz bus).The MCU also offers on-chip integration without compromising the low power consumption demands of many 8-bit applications by offering a series of clock source options. The internal clock source (ICS) module provides an accurate, low power internal clock generator, eliminating the need for and cost of an external crystal or oscillator. The 9S08QG8/QG4 MCUs are capable of supporting external clock source inputs from 32kHz up to 20MHz.

The 8bit MCUs are available for the suggested resale price of 89 cents for the MC9S08QG4 and 99 cents for the MC9S08QG8 for 1,000-unit MSRP on the least expensive package.

Freescale provides an out-of-the-box development experience with boards, production-worthy code via software libraries and the CodeWarrior development environment to help customers bring products to market easily and quickly. The 9S08QG8/QG4 devices include a background debugging system and on-chip in-circuit emulation (ICE) with real-time bus capture, to eliminate the need for expensive emulation tools.
