Adding to its growing portfolio of microcontroller solutions for LCD-based applications, Freescale Semiconductor has introduced the MC9S08LG32 MCU family for industrial applications. Featuring an integrated LCD driver, the 8-bit S08LG MCUs are members of the L family that provides cost-effective LCD control solutions for a wide range of industrial and automotive designs.

The S08LG family provides cost-effective embedded control and user interface solutions for electric metering applications, HVAC controls, digital thermostats, home appliances and exercise equipment. The S08LG devices are also suitable for a wide range of automotive body control applications, such as instrument clusters used in entry-level vehicles for emerging markets.

The 5V S08LG devices offer a range of flash memory sizes (up to 32Kbyte) and package options scaling from 48 to 80 pins. The on-chip LCD driver supports displays with up to 296 segments (8 x 37 or 4 x 41 LCD configurations). Flexible LCD module power management configuration helps reduce overall power consumption.

In addition, the highly integrated 8bit MCUs are designed to deliver enhanced EMI and EMC performance through flexible pin reassignment. Simple software configuration enables any LCD pin to be assigned to the front plane (segment) or to the back plane (common). Flexible front and back plane reassignment simplifies PCB layout and makes it easy to optimize designs for robust EMI performance.

"With the introduction of the S08LG family, Freescale is addressing customer demand for 5V LCD MCUs optimized for a wide range of industrial, home appliance and medical applications," said Aiden Mitchell, director of industrial and multi-market MCUs at Freescale. "The S08LG devices provide embedded developers 5V 8bit alternatives to help drive down development cost while helping ensure quality and reliability."

The S08LG family leverages and expands on the extensive suite of hardware and software development tools available today for the S08 families. The CodeWarrior Development Tool Suite and a wide range of third-party development software tools are available to help ease and accelerate application development. Freescale plans to offer cost-effective DEMO9S08LG32 family demonstration boards in Q2 09.

Samples of the MC9S08LG32 MCUs are available to select customers. General market support for automotive is planned for later in Q2 09. Suggested resale pricing in 10,000-unit quantities begins at $1.70 for the MC9S08LG32 and $1.55 for the MC9S08LG16.

The full-featured DEMO9S08LG32 demonstration board (with an MC9S08LG32 MCU in an 80-pin LQFP package) is available at a suggested resale price of $99. Initial versions of the demonstration board are available today to selected customers. General market support is planned for later in Q2 09.
