LDP1WC 250P-16 PLC module programmable controller

LDP1WC 250P-16 PLC module programmable controller

Technical data of product parameters

The MVME240x base board contains two banks of Flash memory. Bank LDP1WC 250P-16
B consists of two 32-pin devices which can be populated with 1MB of
Flash memory. Only 8-bit writes are supported for this bank. Bank A has
four 16-bit Smart Voltage Flash SMT devices. With the 16Mbit Flash
devices, the Flash size is 8MB. A jumper header associated with the first LDP1WC 250P-16
set of eight Flash devices provides a total of 128KB of hardware-protected
boot block. Only 32-bit writes are supported for this bank of Flash. There
will be a jumper to tell the Hawk chip where to fetch the reset vector. When
the jumper is installed, the Hawk chip maps 0xFFF00100 to these sockets Under normal operation, the Flash devices are in “read-only” mode, their
contents are pre-defined, and they are protected against inadvertent writes LDP1WC 250P-16
due to loss of power conditions. However, for programming purposes,
programming voltage is always supplied to the devices and the Flash
contents may be modified by executing the proper program command
sequence. Refer to the PFLASH command in the PPCbug Debugging
Package User’s Manual for further device-specific information on
modifying Flash contents.The SMC provides the interface for two blocks of ROM/Flash. Access
times to ROM/Flash are programmable for each block. Access times are
also affected by block width. The following tables in this subsection show
access times for ROM/Flash when configured for different device access
times.
