On-Card Memory Configuration

The PmT1 and PmE1 module provides one 32-pin flash socket, an EEPROM, and one RAM configuration. Off-card memory may be accessed via the PMC/PCI interface.

SOCKETED FLASH

The PmT1 and PmE1 modules have a 32-pin PLCC socket for a byte-wide read-only flash. Up to 512-kilobytes of flash may be installed. The socketed flash occupies physical address space FFF0,0000-FFFF,FFFF16.

Note: To avoid damage, please use the proper tool to remove the PLCC device.

Caution:

!

The MPC860P controls the access time for flash. The default power-up timing allows flash with speeds of 200-nanoseconds or faster. We strongly suggest that you use the default timing because of the inherent risks of optimizing timing for a specific configuration, and because of the fact that flash may be cached.

The monitor resides within this socketed device (ROM address: 0x0 - 0x30000) and should not be overwritten.

I2C EEPROM

Another memory device on the PmT1 and PmE1 is a 16-kilobit serial EEPROM. It is internally organized as 1Kx16 and is accessed through the I2C interface pins on the MPC860P. The EEPROM supports a sixteen-byte page write mode and a self-timed write cycle. It provides a minimum endurance of 100,000 cycles and a minimum data retention of 100 years.

The I2C interface consists of the Serial Clock (SCL) and the Serial Data (SDA) lines, which are controlled by bits in the PBDIR and PBDAT registers, and accessible with longword read/write.
