The device has an on-chip 1024 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.

9 Fifteen Code option bits are also available to meet user's requirements. with enhanced OTP-ROM features, the EM78P153K provides a convenient way of developing and verifying user's programs. Moreover, this OTP device offers the advantages of easy and effective program updates, using development and programming tools. Users can avail of the ELAN Writer to easily program their development code. 2 Features CPU configuration Crystal mode: 1k 13 bits on-chip ROM DC ~ 20 MHz / 2clks @ 5V. 32 8 bits on-chip registers (SRAM, general DC ~ 8 MHz / 2clks @ 3V. purpose) DC ~ 4 MHz / 2clks @ 5-level stacks for subroutine nesting ERC mode: Less than mA at 5V / 4 MHz DC ~ 2 MHz / 2clks @ Typically 15 A at 3V / 32kHz Peripheral configuration Typically 1 A during Sleep mode 8-Bit Real Time Clock/Counter (TCC) with selective signal sources, trigger edges, and I/O port configuration overflow interrupt 2 bidirectional I/O ports : P5, P6 Power-on reset and 3 programmable level 12 I/O pins voltage reset Wake-up port : P6 POR: (Default), LVR.
