AT30TSE004A-MAA5M-T Product Details


The Atmel® AT30TSE004A-MAA5M-T is a combination Serial EEPROM and temperature sensor device containing 4096- bits of Serially Electrically Erasable and Programmable Read-Only Memory (EEPROM) organized as 512-bytes of eight bits each. The Serial EEPROM operation is tailored specifically for DRAM memory modules with Serial Presence Detect (SPD) to store a module’s vital product data such as the module’s size, speed, voltage, data width, and timing parameters. The AT30TSE004A-MAA5M-T is protocol compatible with the legacy JEDEC TSE2002av specification (2-Kbit) devices enabling the AT30TSE004A-MAA5M-T to be utilized in legacy applications without any software changes. The Serial EEPROM deploys special software commands to allow users to identify and set which half of the memory the internal address counter is located. This special page addressing method used to select the upper or lower half of the Serial EEPROM is the key to the legacy compatibility; however, there is one minor exception to the legacy compatibility as the AT30TSE004A-MAA5M-T does not support the Permanent Write Protection feature because it was removed from the JEDEC TSE2004a (DDR4) specification. In addition, the Serial EEPROM incorporates a Reversible Software Write Protection (RSWP) feature enabling the ability to selectively write protect any or all of the four 128-byte quadrants. Once the RSWP is set, it can only be reversed by sending a special software command sequence. The integrated temperature sensor converts temperatures from -20C to +125C to a digital word and provides an accuracy of ±1°C (max.) in the temperature range +75C to +95C. The temperature sensor continuously monitors temperature and updates the data in the Temperature Register at least eight times per second. The temperature data is latched internally by the device and may be read by software via a bus Master at anytime (even when the Serial EEPROM is busy writing data to the memory). The AT30TSE004A-MAA5M-T incorporates flexible user programmable internal registers to configure the temperature sensor’s performance and response to over and under temperature conditions. The device contains flexible programmable high, low, and critical temperature limits. The EVENT pin is an active low output and can be configured to operate as an Interrupt or as a Comparator output. The Manufacturer and Device ID Registers provide the ability to confirm the identity of the device. The AT30TSE004A-MAA5M-T supports the industry standard 2-wire I 2 C FM plus (Fast Mode +) serial interface allowing device communication to operate up to 1MHz. A bus timeout feature is supported for both temperature sensor and Serial EEPROM operations to help prevent system lockups. The AT30TSE004A-MAA5M-T is available in space saving 8-lead UDFN and WDFN packages. The UDFN is the recommended and preferred package.
