EM78P5840N/41N/42N
8-Bit Microcontrollers
1 General Description
The EM78P5840N/41N/42N series are 8-bit RISC architecture microcontroller devices
designed and developed with low-power, high-speed CMOS technology. Each of these
devices has on-chip 4K×13-bit Electrical One Time Programmable Read Only Memory
(OTP-ROM). It provides a protection bit to prevent intrusion of user’s OTP memory
code as well as from unwanted external accesses. A number of one-time
programmable option bits are also available to meet user’s application requirements.
Functional flexibility of these integrated ICs is enhanced with their internal special
features such as watchdog timer (WDT), program OTP-ROM, RAM, programmable
real-time clock/counter, internal interrupt, power down mode, dual PWM (Pulse Width
Modulation), 8-channel 10-bit A/D converter, and tri-state I/O.
NOTE
Refer to the Application Notes provided in the Appendix for important reminders before
using the microcontroller described herein.
Convention on tables used to describe register attributes (bit number, bit name, type,
etc.), are also provided in the Appendix.
2 Features
2.1 CPU
„ Operating voltage: 2.2V~5.5V at the main CLK (less than 3.58MHz)
Main CLK fSYS < 3.58MHz: 2.2V
Main CLK fSYS = 14.3MHz: 3.6V
„ IRC mode: 4MHz, 2MHz
Voltage deviation: 5% (2.3V~5.5V)
Process deviation: Typ. 3%, Max. 5%
Temperature deviation: 5% (-40°C~85°C)
„ 4K x 13 OTP-ROM
„ 144 x 8 general propose RAM
„ 19 bi-directional and three input-only general purpose I/O
„ 8-level stack for subroutine nesting
„ 8-bit real time clock/counter (TCC)
„ One 8-bit counter interrupt
„ On-chip watchdog timer (WDT)
„ Single-instruction cycle commands
