Overview
The MC34708 Power Management
Integrated Circuit (PMIC) represents a
complete system power solution in a
single package, designed specifically
for use with the Freescale i.MX50/53
families. It integrates six multi-mode
buck regulators and eight LDO
regulators for direct supply of the
processor core, memory and
peripherals. This device is powered by
SMARTMOS technology.
The USB switch enables the use of a
single, mini or micro USB connector for
USB, UART and audio connections. It
automatically identifies the type of
device connected. In addition, the
MC34708 also integrates a real time
clock, coin cell charger, a 16-channel
10-bit ADC, 5.0 V USB boost regulator,
two PWM outputs, touch-screen
interface, general purpose LED drivers
and four GPIOs.
The MC34708 is available in pin
compatible 8x8 and 13x13 packages.

Analog Product Selector Guide
The i.MX53 family is optimized for both
performance and power to meet the demands
of high-end advanced applications. An
integrated display controller, 1080p HD video
decode and 720p video encode, enhanced
graphics and connectivity features make the
i.MX53 ideal for applications which require
rich user interfaces with high color
displays.The i.MX50 family supports both
LCD and EPD displays to allow customers the
flexibility in designing their system.
The supported memories include mDDR,
DDR2, and LP-DDR2, SD/MMC, and rawNAND with up to 32 bit ECC. Connectivity
features like dual USB with PHY and Fast
Ethernet Controller allow customers to
connect to the interfaces they need.
Benefits
