OKI - MSM83C154s - IC. Hayes 04-00119 V2.5 - High Performance 8-Bit CMOS Microcontroller, 44 Pins PLCC, New The code Hayes copyright P/N: 04-00119 V2.5 refers to the programmed firmware or read-only memory (ROM) contained within a specific integrated circuit (IC) used in vintage Hayes Microcomputer Products networking equipment. Hayes Microcomputer Products, the company famous for creating the "AT" command set that became the industry standard for modems before becoming acquired by Zoom Telephonics now e2Companies, Inc. The OKI MSM83C154s is a high-performance 8-bit CMOS microcontroller featuring internal Mask ROM (MROM). Designed for low-power consumption and high-speed operation (up to 12 MHz or 24 MHz depending on version), it is often used in embedded, industrial applications. Key Specifications & Features: • Manufacturer: OKI (Oki Electric Industry) for Hayes Microcomputer Products • Type: 8-bit Microcontroller (MCU) • Memory: Internal ROM (Mask ROM) • Clock Speed: 12 MHz (standard) or up to 24 MHz (S-series) • Operating Voltage: Low power CMOS Technology • Package: 44-pin PLCC - 44-pin QFJ (QFJ44-P-S650-1.27) (Product name: MSM80C154SJS/ MSM83C154S-xxxJS) • Series: Part of the 80C51/80C31-compatible family Note: Functionality: The MSM83C154 is similar to the MSM80C154, but contains internal program memory (ROM), while the 80C154 is ROMless. These chips often feature bit-addressable data memory, specialized registers, and power-down modes to reduce power consumption. Application Areas: It is utilized in systems requiring 8-bit control, such as industrial equipment, consumer electronics, and portable devices needing power management. Pin Compatibility: The device is designed to be compatible with other OKI MSM80C154/83C154 series microcontrollers, allowing for easy upgrades or swaps. Made in Japan Learn More
