On-Card Memory Configuration:On-card DRAM

I2C EEPROM Operation

The I2C EEPROM supports a bidirectional bus-oriented protocol. The protocol defines any device that sends data onto the bus as a transmitter and the receiving device as the receiver. The device controlling the transfer is the CPU, and the I2C EEPROM being controlled is the slave. The CPU always initiates data transfers and provides the clock for both transmit and receive operations.

Initialization software for the I2C EEPROM should issue a start condition immediately fol- lowed by a stop condition to reset EEPROM to a known state, since the chip maintains its state even between power-ups.

Emerson Memory Map

The following memory map convention has been established by Emerson for data storage within the I2C EEPROM. This map allows various operating systems to store their boot parameters without affecting each other.

ON-CARD DRAM

The PmT1 and PmE1 support 16-megabyte DRAM configuration four bytes wide, for data storage. On-card RAM occupies physical addresses starting at 0000,000016.

Note: All accesses to on-card DRAM must be aligned to natural boundaries. For example, byte accesses must be aligned to byte boundaries, word accesses to word boundaries, and long-word accesses to long-word bound- aries.

The DRAM is controlled by the MPC860P DRAM controller. The controller may be pro- grammed for most memory sizes and speeds, block sizes from 32-kilobytes to 4-gigabytes, and write protection.

In addition to the basic DRAM control functions the MPC860P chip provides several addi- tional DRAM-related functions. Performance enhancing features include: programmable delay insertion for controlling RAS recovery time, RAS low time, CAS setup before RAS time, row address hold time, CAS recovery time, CAS pulse width, CAS access time, and address access time.
