S27KL0642DPBHB023

The S27KL0642DPBHB023 from Infineon Technologies is a 64Mb (8MB) HyperRAM™ memory device that provides external working memory for compatible embedded systems. It features a HyperBus™ interface and integrated self-refresh.

The device supports clock frequencies up to 166MHz, operates from a 2.7–3.6V supply, and accommodates temperatures from −40°C to +105°C. It is supplied in a 24-ball FBGA package measuring 6 × 8mm for surface-mount assembly.

Key Features

• 64Mb memory capacity: Provides 8MB of volatile storage for application data and temporary buffers.

• HyperBus interface: Supports double-data-rate transfers over an 8-bit data bus.

• Integrated self-refresh: Refreshes the memory internally, with host access subject to the datasheet's timing requirements.

• Compact footprint: The 6 × 8mm FBGA package helps conserve board space.

Potential Applications

Potential uses include embedded display frame buffers, temporary data buffering, and external memory expansion for compatible microcontrollers, processors and FPGA designs. Suitability depends on the host controller, required capacity and application bandwidth.

Selection Notes

Before selecting this part, verify HyperBus controller support, supply voltage, package footprint and timing requirements. Confirm the complete ordering code against your approved BOM, as related variants may differ in specifications.

This device is volatile memory and does not retain data after power is removed. Refer to the manufacturer's datasheet for complete electrical characteristics and integration requirements.
