The **M93C86-RDS6TP** is a specific variant of a serial Microwire EEPROM (Electrically Erasable Programmable Read-Only Memory). It is widely used for non-volatile data storage in automotive and industrial applications. --- ### 1. Key Technical Specifications The part number can be broken down to understand its specific electronic characteristics: | Feature | Specification | | :--- | :--- | | **Memory Size** | 16 Kbit (2048 x 8 bits or 1024 x 16 bits) | | **Interface** | Microwire (3-wire or 4-wire serial) | | **Operating Voltage** | 1.8V to 5.5V | | **Clock Frequency** | Up to 2 MHz | | **Package Type** | TSSOP8 (Thin Shrink Small Outline Package) | | **Temperature Range** | -40°C to +85°C (Industrial Grade) | | **Write Cycles** | 4 million cycles (typical) | | **Data Retention** | 200 Years | --- ### 2. Pin Configuration (TSSOP8) The device uses a standard 8-pin layout to manage power and serial communication: 1. **S (Chip Select):** High level enables the device; low level puts it in low-power standby. 2. **C (Serial Clock):** Used to synchronize the communication. 3. **D (Serial Data Input):** Receives instructions and data. 4. **Q (Serial Data Output):** Outputs data to the microcontroller. 5. **VSS:** Ground. 6. **ORG (Organization):** Sets the memory architecture (x8 or x16). 7. **DU (Don't Use):** Usually left floating or connected to VSS. 8. **VCC:** Supply Voltage. --- ### 3. Core Functionality * **User-Configurable Organization:** By toggling the **ORG** pin, the user can choose whether the 16Kb memory is accessed as 2,048 bytes (8-bit) or 1,024 words (16-bit). * **Write Protection:** The device includes software write-protection features to prevent accidental data erasure. * **Sequential Read:** It supports reading the entire memory contents via a single instruction by continuously providing clock pulses. * **Self-Timed Write Cycle:** Once a write command is received, the chip manages the internal high-voltage timing required to change the memory cells automatically. --- ### 4. Part Number Breakdown The suffix `RDS6TP` provides specific logistics and packaging info: * **R:** 1.8V to 5.5V operating range. * **DS:** TSSOP8 package (3mm width). * **6:** Industrial temperature range (-40 to +85°C). * **TP:** Tape & Reel packaging (for automated assembly). ---
