The HY57V654020BTC-6DR-A is a high-density SDRAM (Synchronous Dynamic Random Access Memory) manufactured by SK hynix, featuring a 16Mx4 bit configuration for a total of 64 Megabits or 8 Megabytes of storage. This component operates at a stringent 6-ns cycle time, with a PC167 rating, indicative of its high performance suitable for computing applications requiring rapid memory access. The CL3 rating denotes a CAS latency of 3 cycles, balancing speed and reliability in data transactions. Packaged in a TSOP (Thin Small Outline Package), this memory module is designed for applications that demand high-speed data transfer rates and lower power consumption, such as advanced personal computers, servers, and telecommunications equipment. Its synchronous operation, aligned with the system clock, enables more predictable timing for data access, enhancing the overall efficiency of the system in which it is deployed.
