Technical Data

Freescale Semiconductor, Inc. reserves the right to change the detail specifications,

as may be required, to permit improvements in the design of its products.

Integrated Quad Half-bridge and

Triple High Side with Embedded

MCU and LIN for High End

Mirror

includes a high performance HC08 microcontroller with a

SMARTMOS

a timer, enhanced serial communications interface (ESCI), a 10 bit

analog-to-digital converter (ADC), serial peripheral interface (SPI)

(only internal), and an internal clock generator module (ICG). 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.

application performance adjustments and space saving PCB design.

It is well suited for the control of automotive high end mirrors.

Features

• High performance M68HC908EY16 core

• 16K bytes of on-chip flash memory, 512 bytes of RAM

• Two 16-bit, 2-channel timers

• LIN physical layer interface

• Autonomous MCU watchdog / MCU supervision

• One analog input with switchable current source

• Four low RDS(ON) half-bridge outputs

• Three low RDS(ON) high side outputs

• Wake-up and 2/3-pin hall-effect sensor input

• 12 microcontroller I/Os

The 908E621 is an integrated single package solution that

The single package solution, together with LIN, provides optimal

analog control IC. The HC08 includes flash memory,
