64MB/128MB/256MB/512MB Secure Digital Card Description
ESSDC64 ESSDC128 ESSDC256 ESSDC512 different memory capacities from 64MB 512MB Secure Digital Card. They non-volatile, which means external power required retain information stored these. Besides, They also solid-state device that without moving parts skip break down. ESMSDC64 ESMSDC128 ESMSDC256 ESMSDC512 offer incredible combination fast data transfer, great flexibility, excellent security incredibly small size.
Operating Voltage: 2.7V 3.6V Operating Temperature: Data Transfer Rate: Average 2MB/s Durability: 10,000 insertion/removal cycles Mechanical Write Protection Switch Host allows MultiMediaCard upward compatibility Form Factor: 24mm 32mm 2.1mm
