3 Functional Description

Onboard Bank A Flash

The PrPMC800/800ET contains one bank of 32MB of flash memory on Xport 0 configured for 16-bit mode. Bank A consists of two Intel StrataFlash (28F128J3A) +3.3 volt devices configured to operate in 8-bit mode. These Intel StrataFlash devices support page read mode operations with an 8-byte page size per device.

Optional Bank B Flash

The signal interface for the Harrier Xport 1, configured to operate in Hawk 16-bit address/data mode, is routed to the PMC P14 connector to support an optional 16-bit flash bank B on the baseboard. The address multiplexing of the Hawk mode can address up to 512MB, but device loading may restrict this size to less than that. The reset vector may be sourced by either bank A or bank B depending on the state of the Harrier Xport reset vector control bits (RVEN0/RVEN1). When the RVEN0 bit is set, address range $FFF00000-$FFFFFFFF maps to bank A. When RVEN0 bit is cleared and the RVEN1 bit is set, the address range $FFF00000- $FFFFFFFF maps to bank B. The default state uses bank A for the reset vector. Bank B may be selected by connecting the BANKB_SEL pin on P14 to +3.3V.

Xport 1 may be configured to operate in the normal data byte ordering mode where the data alternates every byte instead of every forth byte (Hawk data mode). The data ordering mode is controlled by one of the onboard jumpers.

ECC Memory

The PrPMC800/800ET supports onboard ECC SDRAM configured as explained below.

Onboard SDRAM

The PrPMC800/800ET onboard ECC SDRAM memory, bank A, is configured as one bank of nine 8-bit wide, +3.3V SDRAM devices in 54-pin TSOPII packages. The total onboard memory size can be 64MB, 128MB, 256MB, or 512MB depending on the memory type used. The SDRAM memory is controlled by the Harrier ASIC which provides single-bit error correction and double-bit error detection. ECC is calculated over 72-bits. Refer to the Harrier ASIC Programmer’s Reference Guide for additional information and programming details. The SDRAM memory bus operates at the same speed as the processor bus.

SROM

The PrPMC800/800ET module contains two 8Kb serial EEPROM devices (AT24C64) and one 256 byte serial EEPROM device (AT24C02) onboard. One 8Kb serial EEPROM provides for Vital Product Data (VPD) storage of the module hardware configuration, and the other 8Kb device provides storage for user configuration data. The contents of the devices are accessed by providing a two-byte address with the same device ID, instead of the standard one-byte address as used in the 256 byte devices. The 256 byte device provides for Serial Presence Detect (SPD) memory configuration information. The Serial EEPROM’s are accessed through I2C port 0 in the Harrier ASIC. Refer to Appendix B of the PrPMC800/800ET Processor PMC Module Programmer’s Reference Guide for information on the contents of the VPD and SPD.
