REVISION CHANGES FROM ENG BOARD TO PILOT REVISION BOARD
10/19/1999
I. Purpose –
There are differences between the ENG and PILOT revisions of the MPC8260ADS board
which may impact Third Party Developers’ BSP’s and/or preliminary application
development. This document lists the features of the new PILOT board, then details the
changes between the ENG and PILOT revisions. For complete information on the
MPC8260ADS, refer to the MPC8260ADS User’s Manual, Rev 0.213, dated November,
1999 at:
http://www.mot.com/netcomm).
The ENG board is the 1
st
revision of the board, the final of these will have been shipped in
November, 1999. The PILOT board is the 2
nd
revision of the board, due to begin shipping
in November 1999. Both boards have a sticker which clearly indicates if they are ENG or
PILOT. The ENG revision’s sticker is located between DS1 and LD16. The PILOT
revision’s sticker is located just above the ATM phy, U1.
II. Features of the new PILOT board:
*64-bit MPC8260, running @ 66MHz external bus frequency.
*16 MByte, Unbuffered, 168 pin Synchronous Dram DIMM, residing on 60X bus,
controlled by SDRAM machine 1. Support for 64 MBytes DIMM (single-bank 1only).
Optional address Latch - Multiplexer is required if an L2-cache module is assembled.
*Support for PBI (Page Based Interleaving) in both Single and 60X-Bus 2 modes.
*Support for Automatic DIMM Identification via MPC8260’s I2C port and DIMM’s se-
rial EEPROM.
*Optional 1/2 MByte L2-Cache on-board using 2 MPC2605 Lookaside cache modules.
*8 MByte, 80 pin Flash SIMM, buffered from 60X bus. Support for up to 32 MByte,
controlled by GPCM, with Automatic Flash SIMM identification, via BCSR. Support for
both ON- and OFF-SIMM Flash reset.
*5V/12V VPP for Flash SIMM, Jumper Selectable.
*4 MByte unbuffered SDRAM on Local bus, controlled by SDRAM machine 2, soldered
directly on board.
*Board Control & Status Register - BCSR, controlling board’s operation.
