Technical specification of Motorola MPC755 microprocessor variants in the XPC755B xxnnnTx series, covering electrical parameters, timing, and ordering…
This document provides part‑number‑specific changes to the recommended operating conditions and electrical specifications for the Motorola MPC755 microprocessor family. It lists the affected part numbers, their core and I/O supply voltages, CPU frequencies, temperature range, and detailed DC and AC timing characteristics for both Rev. D and Rev. E devices.
Additional sections include ordering information, part‑marking conventions, and a revision history. The specifications supersede earlier hardware specifications and are intended for system designers and software implementers who need precise electrical parameters for these pilot‑production prototypes.
| Core supply voltage (VDD) | 2.0 V ±100 mV |
|---|---|
| CPU frequency (XPC755BRX350TD) | 350 MHz |
| Die junction temperature range | -40 °C to 105 °C |
The core supply voltage (VDD) is specified as 2.0 V with a tolerance of ±100 mV.
Rev. D devices support 1.8 V, 2.0 V, and 3.3 V I/O voltages, but they do not support the 2.5 V I/O level.
The devices are rated for a junction temperature range from –40 °C to 105 °C.
