71321SA20TF Product Details
71321SA20TF Overview
As far as memory types are concerned, RAM, SDR, SRAM is considered to be its memory type. In the case of TQFP, it is embedded within the case. A memory chip with a capacity of 2kB is used on this device. On the chip, there are 64 terminations that are planted. The part supports at least 1 functions to ensure a comprehensive working process. In order to function properly, this ic memory chip should be powered by a voltage of 5V. The memory device has an 64-pin package, which encloses it in a small package. I have noticed that the memory device has 64 pins, which indicates that it has 64 locations in the memory. According to the datasheet, this memory chip operates at an operating voltage of 5V. In this chip, the Surface Mount mounting method is used, a straightforward, high-efficiency mounting method. In terms of its nominal supply current, this memory component has a rating of 250mA. The memory chip has 2 ports for granting read/write access to one memory address. There is only a single power supply required for this memory chip. There are I/O ports on this memory ics that have COMMON-bit memory mapping. Temperatures below 0°C should not be used with this memory ics. It is recommended that operation of the part be restricted to temperatures not exceeding 70°C, otherwise damage to the part may occur as a result of overheating. It is recommended that this part be supplied with at least 4.5V volts. The operating voltage shall not exceed 5.5V.
