The **M93C86-RDS6TP/S** is a specific variant of the 16-Kbit serial Microwire EEPROM manufactured by **STMicroelectronics**. It is widely used in automotive and industrial applications for non-volatile data storage. --- ## 1. Technical Specifications The part number encodes specific characteristics regarding its memory capacity, voltage range, and physical packaging. | Feature | Specification | | :--- | :--- | | **Memory Size** | 16 Kbit (2048 x 8 bits or 1024 x 16 bits) | | **Interface** | Microwire (3-wire serial interface) | | **Clock Frequency** | 2 MHz | | **Operating Voltage** | 1.8V to 5.5V | | **Package Type** | TSSOP8 (Thin Shrink Small Outline Package) | | **Temperature Range** | -40°C to +85°C (Industrial Grade) | | **Write Cycles** | 4 million write cycles | | **Data Retention** | 200 years | --- ## 2. Pin Configuration (TSSOP8) The device uses a standard 8-pin layout for communication and power. | Pin Number | Symbol | Description | | :--- | :--- | :--- | | 1 | **S** | Chip Select (Active High) | | 2 | **C** | Serial Clock | | 3 | **D** | Serial Data Input | | 4 | **Q** | Serial Data Output | | 5 | **Vss** | Ground | | 6 | **ORG** | Internal Organization (Selects x8 or x16 mode) | | 7 | **WC** | Write Control (Hardware Write Protection) | | 8 | **Vcc** | Supply Voltage | --- ## 3. Key Electronic Features ### Organization (ORG Pin) The memory can be configured in two ways depending on the logic level of the ORG pin: * **ORG at Vcc:** 1024 words of 16 bits each. * **ORG at Vss (or floating):** 2048 words of 8 bits each. ### Write Protection (WC Pin) This pin provides hardware-level security. When the **WC** pin is held high (Vcc), the write operations to the memory array are disabled, preventing accidental data corruption. ### Low Power Consumption The device is optimized for battery-powered applications, featuring: * **Active Read Current:** 400 µA (max) * **Standby Current:** 1 µA (max at 1.8V) --- ## 4. Part Number Breakdown The suffix **RDS6TP/S** provides information about the manufacturing process and packaging: * **R:** Operating voltage range (1.8V to 5.5V). * **DS:** TSSOP8 package (3mm width). * **6:** Industrial temperature range (-40 to 85°C). * **TP:** Tape and Reel packaging. * **S:** Refers to a specific "Standard" or "Shrink" process technology (often indicating halogen-free or ECOPACK2 compliance).
