Device description:

The S27KL0642GABHI033 and S27KL0642GABHA020 are both 64Mbit pseudo-static random access memory (PSRAM) in 24-FBGA pin packages. The HYPERRAM™ device is a high-speed CMOS, self-refreshing DRAM with xSPI (Octal) interface. DRAM arrays use dynamic cells that need to be refreshed periodically. When the memory is not actively read or written by the xSPI interface master (host), the refresh control logic within the device manages the refresh operation on the DRAM array. Since the host does not need to manage any refresh operations, it appears to the host that the DRAM array uses static units to retain data without refreshing. Therefore, memory is more accurately described as pseudo-static RAM (PSRAM).

Since DRAM units cannot refresh during read or write transactions, the host is required to limit the read or write burst transmission length to allow for internal logical refresh operations when needed. The host must limit the duration of the transaction and allow additional initial access delays at the start of a new transaction if memory indicates that a refresh operation is required.

Key features:

Compact form factor - the FBGA package ensures less board space

• Low pin count - A low pin count helps simplify the design and reduce system costs

• Low power consumption - Mixed sleep modes and partial array refreshes increase energy efficiency

• High throughput - High read/write bandwidth maximizes system performance

HYPERRAM's high throughput, low pin count, small size and high energy efficiency make it ideal for extended storage for a wide range of applications in the automotive, industrial and communications sectors.
