PowerPC 603e at 266 MHz — what the core means for your board
The MPC8245LZU266D is a 32-bit PowerPC 603e processor from NXP's MPC82xx series, clocked at 266 MHz. It integrates an SDRAM controller and PCI interface directly on-chip, making it a single-chip solution for embedded control, telecom line cards, and RAID controller boards that need a memory controller and PCI bus without an external bridge. The 266 MHz core speed sets the processing throughput for your firmware — this is not a high-end PowerPC but a mid-range workhorse for deterministic control tasks.
352-TBGA — rework and board-fit reality
Housed in a 352-TBGA (35x35 mm) package, this part is a BGA with a 1.27 mm ball pitch typical of late-90s/early-2000s PowerPC designs. The 352-LBGA and 352-TBGA variants are the same footprint — the 'T' denotes the tray-shipped version. On the rework bench, a standard BGA rework station with a bottom preheat zone and a top nozzle sized for a 35 mm body handles the removal and replacement.
NXP still manufactures it — no last-time-buy, no end-of-life notice to chase.
SDRAM and PCI — what the integrated controller buys you
The on-chip SDRAM controller supports standard SDRAM devices — no DDR, no DDR2 — so you are limited to PC100/PC133 modules or discrete SDRAM chips. The PCI interface operates at 33 MHz or 66 MHz depending on the system clock configuration, and it handles bus mastering for DMA transfers. If your design needs a graphics accelerator, this part does not include one, so a separate GPU or framebuffer is required.
Rated for 0°C to 105°C ambient, this is a commercial/industrial temperature grade. It will work in a ventilated indoor enclosure or a telecom cabinet.
