Product details
Overview
AT25FS010Y7-YH27-T from Microchip Technology is a 1 Mbit (131,072 × 8) serial SPI Flash memory IC optimized for industrial and commercial low-voltage embedded systems. It operates from 2.7V to 3.6V, supports 50 MHz clock rate, features sector/block/page erase architecture (four 32 KB blocks), and delivers 30 µs/byte typical program time. It is used in firmware storage, boot code retention, and configuration data logging in microcontroller-based edge devices.
For engineers reviewing the AT25FS010Y7-YH27-T datasheet, AT25FS010Y7-YH27-T pinout, AT25FS010Y7-YH27-T application, or AT25FS010Y7-YH27-T equivalent, key selection considerations include its 8-lead Ultra Thin SAP package, hardware/software write protection (WP pin + status register BP bits), HOLD/SO/CS/SCK/SI interface timing compliance with SPI Mode 0/3, and JEDEC-standard product ID read capability.
Technical Context
The AT25FS010Y7-YH27-T implements a synchronous serial peripheral interface as a slave device with separate SI (input) and SO (output) pins, supporting MSB-first transmission and flexible op-codes including FAST READ (0Bh) and standard READ (03h). Its internal architecture divides memory into 512 pages of 256 bytes each, grouped into eight 4 KB sectors per 32 KB block.
It integrates a Power-On Reset (POR) circuit (~1.8 V threshold) to prevent corruption during power-up/down, self-timed erase/program cycles (sector: 50–200 ms; chip: 1.6–4 s), and nonvolatile status register bits (BP0–BP4, WPEN, WEN, RDY) that control block-level write protection and device readiness state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1,048,576 bits (131,072 × 8), sufficient for compact firmware images and parameter tables |
| Supply Voltage Range | 2.7 V to 3.6 V - compatible with 3.3 V logic systems and tolerant of brown-out conditions |
| Max Clock Frequency | 50 MHz - enables high-speed read access without external wait states in MCU interfaces |
| Program Time | 30 µs/byte typical - allows rapid field updates within tight real-time constraints |
| Erase Granularity | 4 KB sectors / 32 KB blocks / full chip - supports modular firmware patching and secure recovery |
| Endurance | 10,000 write cycles typical - suitable for infrequent configuration updates over 10+ year deployments |

| Package | 8-lead Ultra Thin SAP (6.00 mm × 4.90 mm) - space-constrained PCB layouts with thermal efficiency |
Pinout & Package
AT25FS010Y7-YH27-T uses an 8-lead Ultra Thin Small Array Package (SAP) with dual footprint compatibility and non-leaded construction. Pin 1 is marked by a dot on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Active-low enable signal; must be stable before SCK edge; drives device into standby when high |
| SCK | Serial Clock Input | Master-generated clock; defines SPI timing boundaries; requires tWH/tWL ≥ 9 ns |
| SI | Serial Data Input | Receives op-codes, addresses, and program data; MSB-first, sampled on SCK rising edge |
| SO | Serial Data Output | Drives read data and status bits; high-impedance when CS high or HOLD active |
| GND | Ground Reference | Return path for VCC and all I/O; must be low-inductance connection for noise immunity |
| VCC | Power Supply | 2.7–3.6 V supply; decoupling capacitor (0.1 µF) required near pin for transient stability |
| WP | Write Protect Input | Hardware lock for status register writes when WPEN = 1 and WP = low; overrides software protection |
| HOLD | Communication Suspend | Pauses ongoing SPI transfer without resetting sequence; requires SCK low to assert/deassert |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-standard RDID support | Reads manufacturer ID (1Fh) and device ID (66h/01h) via dual op-codes (9Fh/ABh) for automated BOM validation |
| Flexible block write protection | Status register BP bits enable 1/32 to full-array lockout - prevents accidental overwrite of critical boot sectors |
| Self-timed erase/program | No external timing control needed; RDSR polling (RDY bit) provides deterministic completion signaling |
| Dual SPI mode support | Operates in Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1) - interoperable with diverse MCU peripherals |
| Ultra Thin SAP package | 6.00 mm × 4.90 mm footprint with 0.5 mm max height - ideal for portable and IoT endpoint designs |
| Power-on reset protection | Internal POR circuit (~1.8 V threshold) ensures reliable initialization across voltage ramp rates |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the package type and dimensions of the AT25FS010Y7-YH27-T?
The AT25FS010Y7-YH27-T uses an 8-lead Ultra Thin Small Array Package (SAP) with body dimensions of 6.00 mm × 4.90 mm and maximum height of 0.5 mm. This non-leaded, dual-footprint package is distinct from the 8-lead JEDEC SOIC variant and optimized for PCB area and thermal performance in compact designs.
Does the AT25FS010Y7-YH27-T support both SPI Mode 0 and Mode 3?
Yes, the AT25FS010Y7-YH27-T supports both SPI Mode 0 (CPOL = 0, CPHA = 0) and Mode 3 (CPOL = 1, CPHA = 1), as confirmed in its datasheet features section. However, the timing diagrams and functional description explicitly reference Mode 0 operation, and all AC characteristics (e.g., tWH, tWL) are specified for Mode 0.
How does hardware write protection work on the AT25FS010Y7-YH27-T?
Hardware write protection on the AT25FS010Y7-YH27-T is enabled when the WPEN bit in the status register is set to "1" and the WP pin is driven low. This inhibits all writes to the status register - including BP bits and WPEN itself - while allowing reads. If WPEN = 0, the WP pin has no effect, permitting full status register programming.
What is the minimum and maximum supply voltage for reliable operation of the AT25FS010Y7-YH27-T?
The AT25FS010Y7-YH27-T operates reliably from 2.7 V to 3.6 V DC. Absolute maximum rating is 4.2 V, but functional operation outside the 2.7–3.6 V range is not guaranteed. The internal POR circuit activates below ~1.8 V to prevent corruption during power transitions.
Can the AT25FS010Y7-YH27-T be used in place of the AT25FS010N-SH27-T?
No - the AT25FS010Y7-YH27-T and AT25FS010N-SH27-T differ in package type: Y7 denotes 8-lead Ultra Thin SAP, while SH27 denotes 8-lead JEDEC SOIC. They share identical electrical specifications and command set, but their footprints and thermal profiles are incompatible; PCB layout redesign is required for substitution.
