Document Number: MM908E621 Rev 4.0, 6/2007 Freescale Semiconductor Technical Data © Freescale Semiconductor, Inc., 2007. All rights reserved. Integrated Quad Half-Bridge and Triple High-Side with Embedded MCU and LIN for High End Mirror The 908E621 is an integrated single-package solution that includes a high-performance HC08 microcontroller with a SMARTMOSTM analog control IC. The HC08 includes flash memory, a timer, enhanced serial communications interface (ESCI), an analog-to-digital converter (ADC), serial peripheral interface (SPI) (only internal), and an internal clock generator module. The analog control die provides four half-bridge and three high-side outputs with diagnostic functions, a Hall-Effect sensor input, analog inputs, voltage regulator, window watchdog, and local interconnect network (LIN) physical layer. The single-package solution, together with LIN, provides optimal application performance adjustments and space-saving PCB design. It is well suited for the control of automotive high-end mirrors.
