MPC2605 is a single chip, 256KB integrated look-aside cache with copy-back capability designed for PowerPC applications (MPC603 and MPC604). Using 0.38µm technology along with standard cell logic technology, the MPC2605 integrates data, tag, host interface, and least recently used (LRU) memory with a cache controller to provide a 256KB, 512KB, or 1 MB Level 2 cache with one, two, or four chips on a 64-bit PowerPC bus.
The Motorola MPC2605 is a single-chip Level 2 cache memory device featuring 256KB of capacity (expandable to 1MB) with copy-back capability. It utilizes 0.38 um technology and integrates data, tag, host interface, and least recently used (LRU) logic.
| Capacity Options | 256KB, 512KB, or 1 MB |
|---|---|
| Technology Node | 0.38 um |
| Operating Frequency | 66 MHz |
| Power Supply Voltage | 3.3 V +/- 5% |
| Package Type | 241 PBGA |
The device operates with a single 3.3 V power supply, and the absolute maximum rating for this voltage is -0.5 to +4.6 V.
The chip functions correctly between 0 and +125 °C, but it can be stored from -55 to +125 °C.
The HRESET input must be held low for at least 16 clock cycles to ensure proper initialization.
