EM6607

Here are some general descriptions of the EM6607. The EM6607 is a single chip low power, mask programmed CMOS 4-bit microcontroller. It contains ROM, RAM, watchdog timer, oscillation detection circuit,
combined timer / event counter, prescaler, voltage level detector and a number of clock functions. Its low voltage and low power operation make it the most suitable controller for battery, stand alone and mobile equipment. The EM6607 microcontroller is manufactured using EM's Advanced Low Power CMOS Process. In 24 Pin package it is direct replacement for EM6603.
Here are some features of the EM6607. The low Power is typical 1.8A active mode, typical 0.5A standby mode, typical 0.1A sleep mode@ 1.5V, 32kHz, 25 . Low Voltage is 1.2 to 3.3 V. ROM is 2k * 16 (Mask Programmed), and RAM is 96 * 4 (User Read/Write). The EM6607 has 2 clocks per instruction cycle and RISC architecture. And also, the EM6607 has 5 software configurable 4-bit ports and 1 High drive output port. The EM6607 is Up to 20 inputs (5 ports) and Up to 16 outputs (4 ports). The EM6607 has buzzer three tone, Serial Write buffer SWB, Supply Voltage level detection (SVLD), Analogue and timer watchdog, 8 bit timer / event counter, Internal interrupt sources (timer, event counter,prescaler), External interrupt sources (portA + portC).
Here are some typical applications of the TC7W66F. The TC7W66F has sensor interfaces, domestic appliances, clocks, security systems, bicycle computers, automotive controls, TV & audio remote controls, measurement equipment, R/F and IR. control and motor driving
Here are some main operating modes and resets of the TC7W66F. The TC7W66F has Active mode when CPU is running, Standby mode when CPU in Halt, Sleep mode when it is No clock and Reset State, Initial reset on Power-On (POR), External reset pin, Watchdog timer (time-out) reset, Oscillation detection watchdog reset, Reset with input combination on PortA.
