MPC7448 RISC Microprocessor Hardware Specifications, Rev. 4

Freescale Semiconductor

Pinout Listings

Table 11 provides the pinout listing for the MPC7448, 360 HCTE package. The pinouts of the MPC7448

and MPC7447A are compatible, but the requirements regarding the use of the additional power and ground

pins have changed. The MPC7448 requires these pins be connected to the appropriate power or ground

plane to achieve high core frequencies; see Section 9.3, “Connection Recommendations,” for additional

information. As a result, these pins should be connected in all new designs.

Additionally, the MPC7448 may be populated on a board designed for a MPC7447 (or MPC7445 or

MPC7441), provided the core voltage can be made to match the requirements in Table 4 and all pins

defined as ‘no connect’ for the MPC7447 are unterminated, as required by the MPC7457 RISC

Microprocessor Hardware Specifications. The MPC7448 uses pins previously marked ‘no connect’ for the

temperature diode pins and for additional power and ground connections. The additional power and

ground pins are required to achieve high core frequencies and core frequency will be limited if they are

not connected; see Section 9.3, “Connection Recommendations,” for additional information. Because

these ‘no connect’ pins in the MPC7447 360 pin package are not driven in functional mode, an MPC7447

can be populated in an MPC7448 board.

NOTE

Caution must be exercised when performing boundary scan test operations

on a board designed for an MPC7448, but populated with an MPC7447 or

earlier device. This is because in the MPC7447 it is possible to drive the

latches associated with the former ‘no connect’ pins in the MPC7447,

potentially causing contention on those pins. To prevent this, ensure that

these pins are not connected on the board or, if they are connected, ensure

that the states of internal MPC7447 latches do not cause these pins to be

driven during board testing.

For the MPC7448, pins that were defined as the TEST[0:4] factory test signal group on the MPC7447A

and earlier devices have been assigned new functions. For most of these, the termination recommendations

for the TEST[0:4] pins of the MPC7447A are compatible with the MPC7448 and will allow correct

operation with no performance loss. The exception is BVSEL1 (TEST3 on the MPC7447A and earlier

devices), which may require a different termination depending which I/O voltage mode is desired; see

Table 3 for more information.

NOTE

This pinout is not compatible with the MPC750, MPC7400, or MPC7410

360 BGA package.
