STMicroelectronics M95160-RMC6TG

Overview

M95160-RMC6TG from STMicroelectronics is a 16-Kbit serial SPI bus EEPROM organized as 2048 × 8 bits, operating from 1.8 V to 5.5 V supply and supporting 20 MHz clock frequency. It features 32-byte page write capability with ≤5 ms write time, quarter/half/whole array write protection, and >4 million write cycles. It is used in industrial control systems for parameter storage and calibration data retention.

For engineers reviewing the M95160-RMC6TG datasheet, M95160-RMC6TG pinout, M95160-RMC6TG application, or M95160-RMC6TG equivalent, key selection criteria include its 1.8 V minimum VCC, ECOPACK2®-compliant UFDFPN8 package, SPI mode compatibility (CPOL=0/1, CPHA=0/1), and identification page lockability for secure configuration storage.

Technical Context

The device implements a standard SPI interface with four active signals (C, D, Q, S) plus HOLD and W control lines. It supports dual SPI modes (CPOL=0, CPHA=0 and CPOL=1, CPHA=1), latching input on rising clock edge and outputting on falling edge. Internal logic includes a status register with BP1/BP0 bits controlling write-protect granularity and SRWD bit enabling permanent protection.

Memory organization comprises 2 Kbytes of EEPROM with one additional 32-byte Identification Page (available only in M95160-D variants). The device enters Standby Power mode when Chip Select (S) is high, and Active Power mode when S is low - with internal write cycles continuing regardless of S state. Hold functionality suspends communication without deselecting the device.

FAQ

What SPI modes does M95160-RMC6TG support?

M95160-RMC6TG supports two SPI modes: CPOL=0, CPHA=0 and CPOL=1, CPHA=1. In both, data is latched on the rising edge of Serial Clock (C) and output changes on the falling edge. Mode selection depends on host controller configuration - no internal mode switching is required.

How is write protection configured on M95160-RMC6TG?

Write protection is controlled by BP1 and BP0 bits in the Status Register, set via Write Status Register (WRSR) instruction. These bits define protected blocks as quarter (512 B), half (1 KB), or full (2 KB) memory. The W pin provides hardware-level freeze of the current protection setting during active writes.

Does M95160-RMC6TG include an Identification Page, and how is it secured?

Yes - M95160-RMC6TG includes a dedicated 32-byte Identification Page. It can be written like normal memory, then permanently locked in read-only mode using the Lock ID instruction. Once locked, the page cannot be rewritten or erased, ensuring immutability of stored calibration or security data.

What package variant is M95160-RMC6TG, and what are its PCB assembly considerations?

M95160-RMC6TG uses the UFDFPN8 package (2 mm × 3 mm, 0.5 mm pitch) with wettable flanks. Its no-lead design requires stencil-defined solder paste volume and reflow profile optimization for void-free joints. ST provides recommended footprint and land pattern in DocID022580 Rev 8, Section 10.3.
