First in the EP72xx
series of ARM
processors from the EPD
division of Cirrus Logic
. Features of note include:
- EDO DRAM controller
- 37.5kB of on-chip SRAM
- built-in greyscale LCD driver
- dual serial UARTs with optional IrDA LED drive on UART0
- telecom-style CODEC interface
Like all of the 7-series Maverick
parts, an ARM720T
core lies at the heart of this beast.
The main difference between this part and the others in the series is the inclusion of the DRAM
interface and the exclusion of the high-speed DAI
CD-quality CODEC interface. This limitation makes this part suited more for PDA, VoIP
, and other non music related portable products.
The evaluation kit
for this product is the EDB7111-2
. Don't be fooled; the same board is used for the now defunct EP7111
and this part.
