93LC66C-I/ST Typical application Circuitry

93LC66C-I ST

The 93LC66C-I/ST is part of the Microchip Technology Inc. 93XX series, a family of Microwire (3-wire) serial EEPROMs. A wide range of applications requiring non-volatile memory storage are catered for by this series. Specifically, the 93LC66C variant is a 4K-bit EEPROM, offering organized storage as either 256 x 16-bit (word) or 512 x 8-bit (byte), selectable through external ORG pin configuration. The "-I/ST" suffix denotes the industrial temperature range and the TSSOP package type, making this device suitable for applications requiring a compact footprint and operation in environments with extended temperature ranges.

1. Power Supply Voltage (VCC Pin): The 93LC66C-I/ST operates with a supply voltage (VCC) typically ranging from 2.5 volts to 5.5 volts, accommodating both 3.3V and 5V systems. This range allows for flexible integration into various digital systems, ensuring compatibility with both low and standard voltage logic levels. The VCC pin should be connected to the positive supply, with a decoupling capacitor placed close to the device to ensure stable operation.

2. Ground Connection (VSS Pin): The device's ground reference, the VSS pin, has to be linked to the system ground. A solid and low-impedance ground connection is vital for the stable operation of the EEPROM and the integrity of data communication.

3. Serial Data Input and Output (DI, DO Pins): During write operations, data, addresses, and commands are entered into the EEPROM via the DI (Serial Data Input) pin. The DO (Serial Data Output) pin outputs data during read operations. These pins are part of the Microwire interface, which facilitates serial communication with a microcontroller or processor.

4. Serial Clock (SK Pin): The SK (Serial Clock) pin provides the clock signal for synchronizing serial data communication. Data bits are clocked in and out on the rising or falling edges of the clock signal, as defined in the EEPROM's datasheet.

5. Chip Select (CS Pin): The CS (Chip Select) pin enables and disables the device, allowing it to be part of a bus system with multiple devices. Driving the CS pin high initiates communication with the 93LC66C-I/ST, while driving it low terminates the communication, ensuring that the device only responds to commands when specifically addressed.

6. ORG Pin: The ORG (Organization) pin determines the memory organization as either 256 x 16 bits or 512 x 8 bits. The state of this pin (high or low) sets the desired organization mode, which should be configured based on the application's specific memory structure requirements.

7. Write Protect (WP Pin): The WP (Write Protect) pin controls the protection of the entire memory array. When connected to VCC, the memory is protected against write operations, effectively preventing accidental data overwrites or erasure. This feature is especially useful in applications where data integrity is critical.

The power supply, grounding, and serial communication interface must all be carefully considered before implementing the 93LC66C-I/ST in a circuit. Proper configuration of the ORG and WP pins is also crucial for ensuring the desired memory organization and data protection. With its compact package and flexible memory organization, the 93LC66C-I/ST is an excellent choice for applications requiring small, non-volatile storage solutions, such as configuration parameters, device identification, and small data logs.
