Toshiba’s TMP68301 is a single-chip, integrated second mode is the emulation mode. In the controller utilizing the CMOS 68HCO000 emulation mode, the 68HC000 core does not microprocessor as the core processor. Standard operate and the built-in peripheral devices are peripherals circuits required by the 68HCOOO are operated by external bus signals. built into the TMP68301. Built-in circuits include 3 serial interfaces, a parallel interface, 3 timers, The TMP68301 can be used where low-power an interrupt controller and an address decoder. operation or high-performance or low-cost are required. The TMP68301 is usable for a wide The TMP68301 has two operating modes. The variety of applications, such as dot matrix and first is the normal operation mode in which the laser printers, hand-held data terminals and full functionality of the chip is available.
