Product details

64 KB FRAM — the non-volatile memory that writes like RAM

The MSP430FR5849IDAR: Its headline feature is 64 KB of FRAM program memory — a non-volatile storage technology that combines the fast write speed and low power of RAM with the data retention of Flash, without the erase-before-write penalty. This makes it a strong fit for applications that log data frequently, need field firmware updates, or operate on a tight energy budget where every write cycle costs microamps instead of milliamps.

38-pin TSSOP body (6.10 mm wide). Surface-mount.

Frequently asked questions

What is the FRAM size of MSP430FR5849IDAR?

The MSP430FR5849IDAR has 64 KB of FRAM program memory (organized as 64K x 8 bits) plus 2 KB of SRAM. FRAM is non-volatile, so no separate EEPROM is needed for configuration storage.

How to program MSP430FR5849IDAR?

The MSP430FR5849IDAR is programmed via the Spy-Bi-Wire (SBW) two-wire JTAG interface, supported by TI's MSP-FET debugger and Code Composer Studio IDE. The FRAM can be written in-system at full speed without erase cycles, which simplifies field updates.
