Maxim Integrated's DS24B33S: Robust 1-Wire EEPROM

The DS24B33S from Maxim Integrated is a highly reliable, 4096-bit 1-Wire EEPROM (Electrically Erasable Programmable Read-Only Memory) designed for data storage in applications requiring low-power and a small footprint. This durable memory chip utilizes Maxim's unique 1-Wire interface, which simplifies the connectivity by using only one wire for both communication and power supply, making it an ideal choice for applications where pin count and space are at a premium.

With its robust design, the DS24B33S ensures data integrity and security. The EEPROM is partitioned into sixteen pages of 256 bits each, and each page can be individually write-protected or put into EPROM-emulation mode, where bits can only be changed from a 1 to a 0. This flexibility allows for a wide range of data storage applications, from calibration and user preference data to storing identification and authentication credentials.

The DS24B33S is designed to operate over a wide voltage range of 2.8V to 5.25V and is specified for operation from -40°C to +85°C, making it suitable for harsh environments and demanding applications. The device's unique 64-bit serial number, which is factory-lasered into each chip, provides a guaranteed unique identity and can be used for addressability in a multi-device 1-Wire network.

Key features of the DS24B33S include:

• 4096 bits of EEPROM memory organized as 16 pages of 256 bits
• Individual page write-protection and EPROM-emulation mode for data security
• Wide operating voltage range (2.8V to 5.25V)
• Wide operating temperature range (-40°C to +85°C)
• Factory-lasered 64-bit ROM ID for device identification
• Minimalist 1-Wire interface to reduce pin count and simplify board layout

Whether you're developing smart sensors, portable electronics, or any device requiring a compact, non-volatile memory solution, the DS24B33S offers a trusted platform for your data storage needs. Maxim Integrated's commitment to quality and reliability ensures that the DS24B33S will perform consistently, delivering the data security and endurance required for today's electronics.
