MTFC4GACAJCN-1M

MTFC4GACAJCN-1M is the 4 GB member of Micron’s PS8225-controller e·MMC line, rated -25°C to +85°C operating, in a 153-ball VFBGA measuring 11.5 x 13.0 x 1.0 mm.

Key figures

• Nominal capacity 4 GB; the ECSD register’s SEC_COUNT is 0x00748000.
• Sequential HS400 read up to 160 MB/s, write up to 14 MB/s (typical, x8 bus, 1 MB chunk).
• Package: 153-ball VFBGA, 11.5 mm x 13.0 mm x 1.0 mm (package code CN).
• Supply: VCC 2.7-3.6 V; VCCQ dual 1.65-1.95 V or 2.7-3.6 V.
• JEDEC/MMC standard version 5.0-compliant (JESD84-B50), HS400/HS200 modes.

Capacity: register recomputation

MemSignal recomputed the register to show the 4 GB user area as the document’s own arithmetic: SEC_COUNT 0x00748000 is 7,635,968 sectors of 512 bytes, i.e. 3,909,091,328 bytes = 3728 MB (1024-base). The maximum enhanced-area size register (MAX_ENH_SIZE_MULT 0x0000E9 with HC_WP_GRP_SIZE 0x10 and HC_ERASE_GRP_SIZE 0x01) recomputes to 1864 MB. These are arithmetic from the register constants, printed alongside the nominal 4 GB.

What this document does not claim

The datasheet carries no product-status or lifecycle field for this code, and we did not confirm it against the manufacturer’s part catalog in this batch, so the Lifecycle field is left empty and no Active/Obsolete claim is published here. The document carries no endurance figure, no NAND flash type for this part, and no vehicle-grade qualification statement of any kind.

Source and datasheet link

Every figure above is taken from Micron e·MMC (PS8225 controller, JESD84-B50 v5.0) Data Sheet Rev. D 2/16 EN (23 pages · md5 f6a77b08feb7480af2df8aae5106be6e · last row of the revision-history table Rev.D 2/16 Production release), a confidential manufacturer datasheet that reached us through the supply chain; no byte-for-byte public copy was found, so no datasheet link is published.

Who makes it

Micron Technology, Inc., founded 1978 and headquartered in Boise, Idaho, is the manufacturer of record for this e·MMC family.
