Infineon Technologies S80KS2563GABHB023

Overview

S80KS2563GABHB023 from Infineon Technologies is a 256 Mb self-refresh DRAM (HYPERRAM™) with Octal xSPI interface, operating at 1.8 V. It delivers 400 MBps data throughput at 200 MHz DDR clock, supports linear/wrapped burst lengths (16–128 bytes), and integrates on-die refresh control to emulate PSRAM behavior in embedded microcontroller systems requiring high-density, low-pin-count external memory.

For engineers reviewing the S80KS2563GABHB023 datasheet, S80KS2563GABHB023 pinout, S80KS2563GABHB023 application, or S80KS2563GABHB023 equivalent, key selection criteria include xSPI command compatibility, RWDS timing for refresh latency indication, configurable drive strength, hybrid sleep/deep power down modes, and AEC-Q100 Grade 2 qualification for automotive infotainment and ADAS domain controllers.

Technical Context

The S80KS2563GABHB023 implements an xSPI-compliant Octal DDR interface with 11–12 signal lines (CK/CK#, CS#, DQ[7:0], RWDS, RESET#), using LV-CMOS signaling at 1.8 V. Its internal DRAM array employs 25-nm process technology and embeds autonomous refresh logic that eliminates host-managed refresh cycles.

Read/write transactions begin with a 16-bit command (dual 8-bit opcode), support variable initial latency (tACC = 35 ns), and use RWDS bidirectionally - as output to signal refresh hold time (tRFH) before read data, and as input write mask during writes. Burst configurations are register-programmable and include hybrid (wrapped + linear) mode.

FAQ

What is the function of the RWDS pin during read and write operations?

RWDS serves dual roles: during reads, it outputs a HIGH pulse before valid data to indicate required refresh hold time (tRFH); during writes, it acts as an input mask signal controlling which DQ[7:0] bits are written. This bidirectional behavior is integral to xSPI timing compliance and cannot be omitted or repurposed.

Does S80KS2563GABHB023 require external refresh management from the host controller?

No. The device contains fully autonomous self-refresh logic that executes internal DRAM refresh cycles without host intervention. The host only needs to observe RWDS-driven latency extensions and avoid exceeding maximum burst duration limits - making it functionally equivalent to PSRAM in software abstraction.

Can this part operate with single-ended clock only, or is differential clock mandatory?

Single-ended clock (CK only) is fully supported and sufficient for most applications. Differential clock (CK/CK#) is optional and improves noise immunity in electrically noisy environments such as automotive powertrain or chassis domains - no functional difference in timing or command execution.

What package variant does S80KS2563GABHB023 use, and is it compatible with standard reflow profiles?

S80KS2563GABHB023 uses a 24-ball FBGA (5 mm × 5 mm, 0.8 mm pitch) compliant with JEDEC MO-270AC. It is qualified for standard lead-free reflow profiles (J-STD-020D), including peak temperatures up to 260 °C, and supports automated optical inspection (AOI) due to its coplanar ball geometry.
