Description

The 78F9177 and µPD78F9177Y are µPD789177, 789177Y Subseries (small, general-purpose) in the 78K/0S Series. The µPD78F9177 replaces the internal ROM of the µPD789176 and µPD789177 with flash memory, while the µPD78F9177Y replaces the ROM of the µPD789176Y and µPD789177Y with flash memory. Because flash memory allows the program to be written and erased electrically with the device mounted on the board, this product is ideal for the evolution stages of system development, small-scale production and rapid development of new products.

The microcontroller also has a variety of input/output peripherals, including timers, serial interfaces, analog-to-digital converters, and digital-to-analog converters.

78F9177 Datasheet

Description

The EM78P156NPJ is an 8 -bit microprocessor designed and developed with low -power, high-speed CMOS technology. It is equipped with 1K*13 -bits Electrical One Time Programmable Read Only Memory (OTP – ROM). It provides three PROTECTION bit to prevent user’s code in the OTP memory from being int ruded. 8 OPTION bits are also available to meet user’s requirements.

With its OTP- ROM feature, the EM78P156N is able to offer a convenient way of developing and verifying user’s programs. Moreover, user can take advantage of EMC Writer to easily program h is development code.

Features

1. Low power consumption:
(1) Less then 2 mA at 5V/4MHz
(2) Typically 20 μA at 3V/32KHz
(3) Typically 1 μA during sleep mode

2. 1K × 13 bits on chip ROM

3. One security register to prevent intrusion of OTP memory codes

4. One configuration register to accommodate user’s requirements

5. 48× 8 bits on chip registers (SRAM, general purpose register)

6. 2 bi-directional I/O ports

7. 5 level stacks for subroutine nesting
