Blank rows are omitted rather than filled with a guess.
The XMC XM25QH128D is a 128M-bit (16M-Byte) serial-interface NOR Flash device running from a single 2.3-3.6 V supply. The industrial grade covers -40°C to +85°C; the ordering guide also lists an Industrial Plus (-40°C to +105°C) code, which is not this grade.
Key figures
- Density 128M-bit / 16M-Byte; 65,536 programmable pages of 256 bytes each.
- Erase granularity: 4,096 erasable 4KB sectors and 256 erasable blocks (32KB/64KB).
- Read: 166MHz Single/Dual/Quad SPI fast read, 108MHz normal read, 108MHz DTR read; QPI supported.
- Reliability: more than 100,000 erase/program cycles; more than 20-year data retention.
- Power: 10µA typical standby, 4mA active read (80MHz Quad I/O), 0.2µA deep power-down.
- Packages: 8-pad WSON (5×6 or 6×8), SOP 208-mil, FOSON 3×3; this profile represents the WSON form.
What this document says about grade
The ordering guide assigns suffix “I” to the Industrial range and “P” to Industrial Plus (-40°C to +105°C); the part number profiled here is tagged Industrial only. The document carries no automotive or qualification statement for this part, and we make no such claim.
Provenance
Every figure above is taken from Wuhan Xinxin (XMC) “XM25QH128D 3V 128M-BIT Serial Flash with Dual/Quad SPI & QPI/DTR” Rev1.2, Issue Date 2024/11/15, 97 页; the geometry figures (65,536 pages × 256 bytes = 16,777,216 bytes = 16M-Byte, and 4,096 × 4KB, 256 × 64KB) are the document’s own printed values, which are internally consistent. We link no public datasheet because our copy has not been byte-verified against a manufacturer-hosted file.
Who makes it
XM25QH128D is made by 武汉新芯集成电路股份有限公司 (Wuhan Xinxin Semiconductor Manufacturing Co., Ltd., “XMC”), which its own company profile states was founded in 2006 in Wuhan as a leading 12-inch specialty-process foundry with a specialty-memory line.
