Product Summary

Toshiba's TMP68301 is a single-chip,integrated controller utilizing the CMOS 68HC000 microprocessor as the core processsor.Standard peripherals circuits required by the 68HC000 are buily into the TMP68301.Built-in circuits include 2 serial interfaces,a parallel interface,3 timers,an in interrupt controller and an address decoder.It has two operating modes.The first is the normal operation mode in which the full functionality of the chip is available.The second mode is the emulation mode.In the emulation mode,the 68HC000 core does not operated and the built-in peripheral devices are operated by external bus signals.It can be used where low-power opreation or high-performance or low-cost are required.It is usable for a wide variety of applications,such as dot matrix and laser printers,hand-held data terminals and embedded controllers.

Features

(1)68HC000 Core based mircroprocessor; (2)3 Asynchronous serial ports with baud rate generators with optional modern control; (3)16 bit parallel interface with optional centronics interface port; (4)3 Timer channels,16 bits each with an 8 bit prescaler; (5)Built-in interrupt controller,3 extermal and 7 internal channels with auto interrupt vector generation.; (6)Sophistivated address decoder,includes relocatable chip select generation for internal registers and external chip selects.; (7)Automatic DTACK generation with 0 to 7 wait states and programmable BERR generation
