The S08LG series is part of Freescale's growing portfolio of automotive instrumentation MCUs with on-chip LCD drivers. The technical features of the S08LG MCU series include:
ï¬ HCS08 CPU core with speed up to 40 MHz ï¬ Up to 32 KB of on-chip dual-bank flash for EEPROM emulation ï¬ Up to 2 KB of on-chip RAM
ï¬ Integrated LCD driver, most configurable to 8 x 37 or 4 x 41 segments ï¬ All LCD pins are multiplexed with general purpose input/output (GPIO) ï¬ For other product specifications and technical data, please refer to Freescale related Web page 
S12HY Example Applications
In order to address the needs of next-generation automotive instrument cluster applications using TFT (Thin Film Transistor) displays, Freescale has expanded its Power ArchitectureTM MCU portfolio with the MPC560xS MCU family, the high-end of six-headsets with high-resolution color displays. meter. The series is also designed to meet the needs of a large number of automotive applications that require 32-bit performance and are cost sensitive.
TFT displays were once limited to high-end vehicles, but their use in low-end and mid-range vehicles is beginning to spread. The MPC560xS product family directly drives TFT displays with a cost-effective, single-chip solution that meets the requirements of both entry-level systems and complex instrument cluster applications. The MPC560xS device not only supports TFT displays in automotive dashboards, but also drives analog meters and liquid crystal displays (LCDs).
The advantage of the MPC560xS MCU is its ability to easily handle complex graphical content such as photos, charts, languages ​​and fonts. The series includes a sophisticated integrated display controller (DCU) driven WVGA (Wide Video Graphics Array) TFT display. An internal display memory can be used to help process graphical content for display on a color TFT panel. If you want to display graphic content on a HVGA (Half-VAG) screen size, you can use the QuadSPI interface in serial flash memory to expand the display memory. The MPC560xS family offers a scalable solution, with 1MB of flash samples now available, and larger and smaller flash versions will be available in the future.
