The 32-bit integrated processor combines a CPU32 core, two-channel DMA controller, serial I/O, timers, and system-integration logic on one device. It operates from a 3.3 V supply and the MC68340FE16V order option is rated for 0 to 16.78 MHz operation over 0 °C to 70 °C. The device provides 32 address lines, a 16-bit external data bus, two USART channels, and IEEE 1149.1 boundary-scan support. The FE suffix specifies a 144-lead ceramic quad flat pack surface-mount package.
