Product details

What this EEPROM is and where it fits

The Renesas X28C513EMB-25 is a 512 Kbit parallel EEPROM organized as 64K × 8 bits, with a 150 ns access time and a 4.5 V supply rail. Packaged in a 32-lead ceramic LCC (32-CLCC), it operates across the full military temperature range of -55°C to 125°C. This part is built for non-volatile firmware or calibration storage in avionics, missile guidance, satellite telemetry, and downhole instrumentation — any environment where a wide temperature swing and a parallel bus interface are non-negotiable.

Military temperature range — deployment context

Rated -55°C to 125°C. The X28HC256FI-90 is rated -40°C to 85°C.

Lifecycle reality — EOL hot, sourced to order

Lifecycle status is EOL hot — discontinued, no last-time-buy window. Available through independent distribution on a quoted-to-order basis.

Write cycle time — 10 ms per word or page

Write cycle time is 10 ms for a word or page write. That is typical for parallel EEPROM of this era — expect firmware updates to take on the order of seconds for a full 64 KB array. Plan your write routine accordingly; a 10 ms polling loop per byte is the safe approach.

Frequently asked questions

Where can I buy X28C513EMB-25 and how is it quoted?

We source X28C513EMB-25 through independent distribution. It is quoted to order against an RFQ; availability and current pricing are confirmed at quote time.

What is the closest functional second-source for X28C513EMB-25?

The X28C010FM-12 is a peer in the same parallel EEPROM family, sharing the 32-CLCC package, 4.5 V supply, and parallel interface. It offers 1 Mbit density at 120 ns access — a denser, faster alternative. Verify pin compatibility before substituting.

Will X28C513EMB-25 drop into a board designed for X28C010FM-12?

Both parts share the 32-CLCC package and 4.5 V supply, but the X28C010FM-12 is 1 Mbit (128K x 8) versus 512 Kbit (64K x 8). If the board decodes the full address range, the X28C513EMB-25 will respond only to the lower 64K addresses. Confirm the address-line mapping before substituting.
