Address Inputs – (MSB:0, LSB:28)
Least significant address bit when asynchronous Data RAMs are used.
Next to least significant address bit when asynchronous Data RAMs are used.
Clock Inputs – CLK2 is for Tag RAM, CLK0, 1, 3, and 4 are for Data RAMs only.
For MPC2106 use all the clocks. For MPC2104 or MPC2105 use CLK0–CLK2
only. For MPC2107 use CLK2 only.
High Data Bus – (MSB:0, LSB:31)
Low Data Bus – (MSB:0, LSB:31)
Data Parity Bits – (MSB:0, LSB:7)
Presence detect bits.
Presence detect bit 0/EEPROM serial clock. (EEPROM option only.)
Presence detect bit 1/EEPROM serial data. (EEPROM option only.)
Data RAM Address Strobe – For MPC2104 or MPC2105 use ADS0 only. For
MPC2106 use ADS0, ADS1.
Data RAM Address Latch Enable – Use for asynchronous Data RAM only.
Data RAM Count Enables – For MPC2104 or MPC2105 use CNTEN0 only. For
MPC2106 use CNTEN0, CNTEN1.
Data RAM Output Enables – For MPC2104 or MPC2105 use COE0 only. For
all others use COE0, COE1.
Data RAM Write Enables – (MSB:0, LSB:7)
Tag RAM clear.
Tag RAM active high match indication.
Tag RAM valid bit.
Tag RAM write enable.
Tag RAM output enable.
Dirty input bit.
Dirty output bit.
Standby pin. Reduces standby power consumption.
Reserved pin.
+ 3.3 V power supply. Must be connected.
