Engineered for Mark V Speedtronic Firmware Storage

This EPROM chip holds critical control firmware for the drive system. It provides non-volatile memory for the GE DS200TCQAF1B DS200TCQAF1BBF component. You will find this 28-pin IC in various Mark V board applications. Unlike multi-chip sets, this single-chip solution simplifies firmware management. It stores complete operational code in one compact package.

Technical Specifications & Physical Dimensions

We designed this memory chip for reliable long-term data retention. The table below presents all verified technical specifications.

Functional Architecture and Pin Layout

This EPROM chip uses a standard JEDEC pinout arrangement. It requires 12.5V on pin 1 for programming mode. You cannot write new data without this elevated voltage. Moreover, the chip includes 28 active pins for addressing and data transfer. These pins connect directly to the board’s memory bus. Consequently, the processor reads firmware within 120 nanoseconds per access.

Installation and Operational Guidelines

The GE DS200TCQAF1B DS200TCQAF1BBF retains data for over 20 years. It needs a UV eraser to clear existing contents. You must insert the chip with pin 1 facing the socket notch. Always use a PLCC extraction tool for removal. This practice prevents bent pins during replacement procedures. Furthermore, the chip supports automatic output tri-state on deselection. This feature allows multiple chips to share the same data bus.

Physical Characteristics and Environmental Limits

This 28-pin IC features a ceramic body with quartz window. You must cover the window with an opaque label after programming. UV light exposure can erase the firmware within 15 minutes. The chip operates reliably across a wide temperature range. In addition, it maintains stable operation between -25°C and 85°C ambient temperature. You can store this chip safely between -65°C and 150°C.
