Ordering Information

Pull-Up Resistor Requirements

The device requires high-resistance pull-up resistors (10 k

Ω is recommended) on open drain type pins

including I2C, Ethernet management MDIO, HRESET and IPIC (integrated programmable interrupt

controller).

Correct operation of the JTAG interface requires configuration of a group of system control pins as

demonstrated in Figure 56. Care must be taken to ensure that these pins are maintained at a valid deasserted

state under normal operating conditions, because most have asynchronous behavior and spurious assertion

that give unpredictable results.

24 Ordering Information

This section presents ordering information for the devices discussed in this document, and it shows an

example of how the parts are marked. Ordering information for the devices fully covered by this document

is provided in Section 24.1, “Part Numbers Fully Addressed by This Document.”

24.1

Part Numbers Fully Addressed by This Document

Table 61 provides the Freescale part numbering nomenclature for the MPC8308 family. Note that the

individual part numbers correspond to a maximum processor core frequency. For available frequencies,

contact your local Freescale sales office. In addition to the maximum processor core frequency, the part

numbering scheme also includes the maximum effective DDR memory speed. Each part number also

contains a revision code which refers to the die mask revision number.

Notes:

1. Contact local Freescale office on availability of parts with C temperature range.

2. See Section 20, “Package and Pin Listings,” for more information on available package types.

3. Processor core frequencies supported by parts addressed by this specification only. Not all parts described in this

specification support all core frequencies. Additionally, parts addressed by Part Number Specifications may support

other maximum core frequencies.
