Product details

1Kbit OTP EPROM with 1-Wire interface — configuration and ID storage

The DS2502P-E48+ is a 1Kbit one-time-programmable EPROM with a 1-Wire interface. Organized as 128 x 8 bits, it stores calibration constants or serial numbers.

OTP memory — no field updates possible

Because the DS2502P-E48+ uses EPROM - OTP technology, each bit can be programmed only once. There is no erase cycle.

1-Wire interface — minimal pin count, specific master required

The 1-Wire interface uses a single data line plus ground for communication. The host system must include a 1-Wire master controller.

Lifecycle and sourcing — active production, no obsolescence concern

The DS2502P-E48+ carries an Active lifecycle status with ROHS3 compliance.

Frequently asked questions

What is the memory size of the DS2502P-E48+?

The DS2502P-E48+ has a 1Kbit memory organized as 128 x 8 bits. This is a one-time-programmable EPROM, so the entire array is written once and cannot be erased.

What is the DS2502P-E48+ equivalent or alternative?

The DS2502P-E48+ is a specific 1Kbit OTP EPROM in the DS2502 family with a 1-Wire interface. Other members of the DS2502 family (e.g., DS2502, DS2502-E48) share the same pinout and protocol but may differ in pre-programmed content or density. For a pin-compatible alternative, look at other DS2502 variants with the same 6-TSOC package and 1-Wire interface.
