Frequently Asked Questions
What interface does the 11AA020T-I/MNY use for communication?
The 11AA020T-I/MNY uses Microchip's single-wire UNI/O serial interface, which requires only one data line plus ground for full bidirectional communication. This minimizes the pin count on the host microcontroller and simplifies PCB routing, making it ideal for space-constrained applications where GPIO pins are limited.
What is the memory capacity and organization of the 11AA020T-I/MNY?
The 11AA020T-I/MNY provides 2Kbit of EEPROM organized as 256 bytes (256x8). This capacity is sufficient for storing device configuration settings, calibration coefficients, serial numbers, or small lookup tables in embedded systems. The maximum clock frequency is 1 MHz, enabling fast serial data transfer.
What is the endurance and data retention of the 11AA020T-I/MNY?
The 11AA020T-I/MNY is rated for a minimum of 1,000,000 write/erase cycles per memory location, ensuring reliable operation in applications that frequently update stored data. Data retention is guaranteed for a minimum of 200 years under standard operating conditions, providing long-term non-volatile storage.
What supply voltage range does the 11AA020T-I/MNY support?
The 11AA020T-I/MNY is designed for 1.8V serial EEPROM operation, making it compatible with modern low-voltage microcontrollers and SoCs. This low supply voltage significantly reduces power consumption in battery-operated IoT devices, wearables, and portable electronics compared to higher-voltage EEPROM alternatives.
What package does the 11AA020T-I/MNY come in and is it RoHS compliant?
The 11AA020T-I/MNY is housed in an 8-pin TDFN (Thin Dual Flat No-lead) package, JESD-30 code R-PDSO-N8, with a Manufacturer Package Code of TDFN-8. The device is RoHS compliant (Pbfree Code: Yes, JESD-609 Code: e4), meeting international environmental regulations for lead-free manufacturing.
