Freescale LC60 Microcontrollers for LCD

Freescale’s MC9S08LC60 (LC60) family of highly integrated, power-efficient 8-bit microcontroller (MCU) devices are optimized for liquid crystal displays (LCDs). The LC60 family features Freescale’s first S08-based flash MCUs to include an integrated LCD driver module with an internal charge pump. Freescale’s LC60 family addresses the display, power, memory and communications requirements of portable LCD applications, handheld consumer and industrial devices. Supporting displays with up to 160 (4×40) segments, LC60 MCUs give developers the flexibility to design LCD applications for portable health care devices, thermostats, exercise equipment, personal diagnostics, calculators, metering equipment, alarm clocks, toys, cameras and many other consumer products.

The LC60 family combines a high-performance, low-voltage S08 MCU core (operating at 1.8V-3.6V) with an LCD driver module, a rich set of communications peripherals, dual flash memory arrays and an integrated programmable timer. This high level of integration helps reduce total system cost and board space by providing a configurable, flexible single-chip solution that minimizes the need for external display driver, memory and timing components and eliminates the need for off-chip EEPROM.

The low-power LC60 LCD device is capable of driving a display using the high performance, low-voltage operation, C compatibility, single-wire background debug mode and on-chip in-circuit emulator (ICE) of the S08 architecture.

The LC60 family features a dual flash memory block for enhanced EEPROM emulation. Eliminating extraneous EEPROM from the system helps reduce system cost and board space. The dual flash block enables continued execution of code out of one block while programming or erasing the other block.

On-chip integrated serial peripheral interface (SPI), serial communications interface (SCI) and inter-IC (12C) modules make it easy to connect LC60 MCUs to external power measurement ICs or to ZigBee(TM) enabled modules for wireless communications applications.

Freescale’s S08 architecture provides an exceptional combination of high performance and low-power operation for cost-sensitive 8-bit embedded applications. Built on Freescale’s 0.25-micron process technology, the S08 architecture is optimized for extreme operating economy with multiple power management modes, making it attractive for battery-powered and handheld applications. Freescale MCUs based on S08 cores also provide an array of advanced features and capabilities, including integrated third-generation flash memory and RAM, multiple serial communication options, on-chip in-circuit emulator (ICE) and high-performance analog functionality.
