The digital system is built on a Marvell PXA320 (Intel XScale
®
) super-pipelined RISC microarchitecture core. The
major features of the core are:
•
CPU clock speed up to 624 MHz with external DDR SDRAM bus speed of 133 MHz.
•
32 KB instruction/32 KB data L1 cache, 256 KB unified L2 cache, 728 KB internal SRAM.
Power Management
The Symbol PL4507 has various power management options depending on the host interface.
USB (SNAPI, USB HID Keyboard, etc.)
The PL4507 automatically manages its power usage, including USB suspend mode. Additionally, when drawing
power from the USB bus, the PL4507 and SE4500 do not exceed the USB limit of 500 mA (see
SSI or RS-232
When using SSI or any RS-232 host interface, set the PL4507 to use one of the following power modes:
•
Continuous Power
: The PL4507 is fully awake and running, even when not in a decode session.
•
Low Power
(default): The PL4507 draws less current at idle than when in Continuous Power mode, and is
more suitable for battery-powered applications. See
Technical Specifications on page 1-7
NOTE
The PL4507 does not use Low Power mode when connected to a USB-based host.
