MPC8343ZQADDB Equivalent & Substitute Parts

Part Overview

The MPC8343ZQADDB is a PowerPC e300 microprocessor IC from the MPC83xx series, featuring a single 32-bit core operating at 266MHz. This embedded processor integrates DDR/DDR2 memory controllers, triple Gigabit Ethernet ports, dual USB 2.0 interfaces with PHY, and additional connectivity options including DUART, I2C, PCI, and SPI. The device is packaged in a 620-HBGA (29x29) ball grid array with exposed pad and operates across the industrial temperature range of 0°C to 105°C.

The MPC8343ZQADDB carries an obsolete product status. Identifying equivalent substitute parts is necessary for ongoing system support, design updates, and procurement continuity when original inventory becomes unavailable.
