EP7211 Datasheet, PDF (4/166 Pages) Cirrus Logic – HIGH-PERFORMANCE ULTRA-LOW-POWER SYSTEM-ON-CHIP WITH LCD CONTROLLER

EP7211
High-Performance Ultra-Low-Power System-on-Chip with LCD Controller
OVERVIEW (cont.)
UARTs to enable these signals to drive an infrared
communication interface directly.
Four synchronous serial interfaces (codec, SSI1,
SSI2, and MCP) are provided. Three of them (codec,
SSI2, and MCP) are multiplexed onto a single set of
interface pins. The full-duplex codec interface allows
direct connection of a standard audio codec chip to
the EP7211, allowing storage and playback of sound.
SSI2 supports both master and slave mode. SSI1
supports master mode only. Both SSI1 and SSI2 sup-
port two industry-standard protocols (SPI^ and
Microwire^) for interfacing standard devices (e.g.,
Max148/9 or AD7811/12 ADC), and for allowing
peripheral expansion (e.g., a digitizer pen). A Multi-
media Codec Port (MCP) can be used to communi-
cate with a multi-functional codec device like the
Philips^ UCB1100.
Packaging
The EP7211 is available in a 208-pin LQFP package
and a 256-ball PBGA package.
System Design
As shown in system block diagram, simply adding
desired memory and peripherals to the highly
integrated EP7211 completes a low-power system
solution. All necessary interface logic is integrated
on-chip.
Development Boards
Cirrus Logic offers an evaluation and development
environment for the EP7211 in the form of the
EDB7211-2 Development Kit.
The EDB7211-2 development kit is a complete devel-
opment platform with access to the features and
capabilities of the EP7211. The kit provides the tools
required for developing and testing the design of a
highly integrated EP7211 system.
