IC697MEM731存储板 英文资料：

IC697MEM731 is a 32-bit CMOS expansion storage board designed specifically for the IC697 CPU 780/781/782/788/789 in the GE Fanuc Series 90-70 series. It is an essential memory component for these CPUs (the motherboard does not have built-in RAM), providing dual storage of SRAM and optional Flash without occupying additional slots.

1、 Core positioning and key characteristics

Core positioning: Providing program/data memory for IC697 CPU 780/781/782/788/789, it is a necessary storage board for these CPUs.

Storage type and capacity:

SRAM: 128KB, 256KB, and 512KB versions.

Flash: The 256KB version comes with 256KB non-volatile Flash built-in, which can save data without the need for a battery when powered off.

Installation method: The daughter board is directly installed in the internal slot of the CPU, sharing the slot with the CPU and not occupying additional rack space.

Power off maintenance:

SRAM: Powered by the IC697ACC701 lithium battery on the CPU motherboard, data is not lost during power outages.

Flash: No battery required, permanently non-volatile storage.

Data verification:

Hardware parity check for SRAM per byte.

CPU background checksum, real-time detection of memory errors.

Compatibility: Fully compatible with programming software such as Series 90-70 standard rack, backplane, and Proficy Machine Edition.

2、 Technical specifications

Series: GE Fanuc Series 90-70

Storage type: 32-bit CMOS SRAM+optional non-volatile Flash

Capacity versions: 128KB SRAM, 256KB SRAM, 512KB SRAM, 256KB SRAM+256KB Flash

Compatible CPU: IC697 CPU 780, 781, 782, 788, 789 (only compatible with this series of CPUs)

Working voltage: Powered by the CPU motherboard, no external power supply required

Power down maintenance: SRAM relies on the motherboard lithium battery; Flash does not require batteries

Installation position: Internal motherboard slot of CPU module

Environmental temperature: 0-60 ℃ (industrial standard)

Error checking: Hardware parity check+CPU background checksum check

3、 Function and application scenarios

Essential memory supply: Provides basic program and data storage for the CPU 78x series, and is a necessary hardware for system operation.

Dual storage architecture: SRAM is used for high-speed program execution; Flash is used to save key programs, formulas, and parameters, and will never be lost when powered off.

Large capacity expansion: The 512KB version meets the memory requirements for complex logic, multitasking, and big data collection.

Typical applications: Large scale PLC control systems in metallurgy, power, chemical, automotive manufacturing, water treatment, and other fields.
