Microchip Launches 25% Cheaper, High‑Density SPI EERAM Memory Family

Microchip Technology Inc., a global leader in semiconductor solutions, has introduced a new family of Serial Peripheral Interface (SPI) EERAM memory devices that deliver up to 25 % cost savings compared to existing serial NVRAM products. The line expands the company’s portfolio to 64 Kbit through 1 Mbit, and for the first time, offers SPI‑based EERAMs. These memory chips are ideal for applications that require data to survive power interruptions, such as smart meters, manufacturing control systems, and other repetitive‑task environments.

EERAM technology keeps the same SPI and I²C interfaces as serial SRAM, enabling data retention without an external battery. By leveraging standard CMOS and flash processes—technologies that benefit from high‑volume production—Microchip keeps unit costs low. In contrast, competitors such as ferroelectric RAM (FRAM) rely on specialty processes that drive up price and create supply volatility.

Available in eight‑pin SOIC, SOIJ, and DFN packages, the following devices are offered in volume production (pricing assumes 10,000 units):

• 48L640 (64‑Kbit SPI) – starting at $0.70
• 48L256 (256‑Kbit SPI) – starting at $1.40
• 48L512 (512‑Kbit SPI) – starting at $2.10
• 48LM01 (1‑Mbit SPI) – starting at $2.90

Products can be purchased through microchipDIRECT or any of Microchip’s authorized distributors. The EERAM family also benefits from Microchip’s obsolescence support, ensuring long‑term availability for customers.
