Product details
Overview
AK6510CM from Asahi Kasei is a 32Kbit (4096 × 8) SPI serial CMOS EEPROM operating from 1.8V to 5.5V, featuring 32-byte page write mode, hardware/software write protection, and -40°C to +85°C industrial temperature range - deployed in embedded microcontroller data logging, sensor calibration storage, and power meter configuration retention.
For engineers reviewing the AK6510CM datasheet, AK6510CM pinout, AK6510CM application, or AK6510CM equivalent, key selection considerations include its 8-pin SSOP package, HOLD/CS/SCK/SI/SO/WP interface timing compliance at 1–5 MHz, block-level write protection granularity, and 1,000,000-cycle endurance per address.
Technical Context
The AK6510CM implements a SPI slave interface with MSB-first transmission, supporting six instructions (READ, WRITE, WREN, WRDI, RDSR, WRSR) over CS-controlled frame boundaries. Its internal architecture integrates charge-pump-based VPP generation for write operations, eliminating external high-voltage supply requirements.
It features dual-layer write protection: software-configurable status register bits (WPEN, BP0/BP1) enabling 1/4, 1/2, or full-array lock, plus hardware WP pin control active when WPEN = 1. The HOLD pin provides synchronous pause/resume of ongoing SPI transfers without clock edge dependency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 32Kbit (4096 × 8), fixed organization - no bank switching or variable addressing modes |
| Supply voltage | 1.8V to 5.5V - supports direct interfacing with 1.8V, 3.3V, and 5V logic systems without level shifters |
| Write endurance | 1,000,000 erase/write cycles per address - validated under page-write conditions at 25°C |
| Data retention | 10 years at +85°C - specified minimum retention under worst-case thermal stress |
| Page write time | ≤5 ms max self-timed programming - includes auto-erase; no external timing control required |
| Standby current | 0.8 µA max at VCC = 5.5V - enables ultra-low-power battery-backed operation |
| SPI clock frequency | 1.0 MHz (1.8V), 2.5 MHz (2.5V), 5.0 MHz (4.5–5.5V) - voltage-scaled timing compliance |
Pinout & Package
AK6510CM uses an 8-pin plastic SSOP (Small Outline Package) with 1.27 mm pitch, JEDEC MS-012AC compliant, footprint compatible with standard SSOP-8 PCB land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select input | Active-low enable for instruction framing; must remain low during full op-code/address/data sequence |
| SCK | Serial Clock input | Master-provided synchronous edge-triggered clock; rising edge samples SI, falling edge drives SO |
| SI | Serial Data input | Receives op-code (8b), address (16b), and data (8b); MSB-first, no parity or framing bits |
| SO | Serial Data output | Tri-state open-drain output; Hi-Z when CS high or during HOLD; outputs memory/status data on falling SCK |
| WP | Write Protect input | Hardware lock for status register writes when WPEN = 1; no effect if WPEN = 0 |
| HOLD | Transfer hold control | Pauses SPI transfer synchronously on low-to-high SCK edge; resumes on next valid SCK edge after HOLD high |
| VCC | Power supply | Single supply powering core logic, EEPROM array, and integrated charge pump - no auxiliary rails needed |
| GND | Ground reference | Common return path for all I/O and internal circuitry; requires low-impedance connection to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Integrated charge-pump VPP generator | Eliminates need for external 12V programming supply - simplifies BOM and layout for space-constrained designs |
| 32-byte page write mode | Enables burst writes up to 32 bytes per 5ms cycle - reduces firmware overhead vs. byte-by-byte programming |
| Configurable block protection | Software-selectable 1/4, 1/2, or full-array lock via BP0/BP1 bits - prevents accidental overwrite of critical calibration data |
| HOLD pin with synchronous resume | Allows master CPU to pause EEPROM access mid-transfer without losing state - essential for real-time interrupt handling |
| Wide VCC range with voltage-scaled timing | Guaranteed AC performance across 1.8V–5.5V without external timing adjustments - supports mixed-voltage systems |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Microchip 25LC320A-I/MS | Same 32Kbit SPI EEPROM, but uses 8-pin MSOP package; lacks HOLD pin and has slower 10ms max write time | No synchronous transfer pause capability - unsuitable for real-time systems requiring deterministic SPI latency | Select when board space permits MSOP and HOLD functionality is unnecessary |
| ON Semiconductor CAT25320VI-GT3 | 32Kbit SPI EEPROM with identical SSOP-8 footprint; supports 10MHz clock at 3.3V but requires 2.5V min supply | Higher speed at 3.3V, but incompatible with 1.8V systems - limits use in ultra-low-power sensor nodes | Select when system operates strictly at 3.3V and needs faster read throughput |
Compared with AK6510CM, the 25LC320A-I/MS omits HOLD and extends write time, reducing suitability for interrupt-driven firmware; the CAT25320VI-GT3 raises minimum VCC to 2.5V, excluding 1.8V battery-powered designs - AK6510CM uniquely balances wide voltage support, HOLD, and SSOP-8 compatibility.

FAQ
What is the maximum SPI clock frequency supported by the AK6510CM at 3.3V operation?
The AK6510CM supports up to 2.5 MHz SPI clock frequency when VCC is between 2.5V and 4.5V - verified per AC Electrical Characteristics Table 3. This allows reliable communication with common 3.3V microcontrollers without requiring clock dividers or timing margin compromises.
Does the AK6510CM require an external high-voltage supply for write operations?
No, the AK6510CM does not require an external high-voltage supply. It integrates an on-chip charge-pump circuit that generates the necessary programming voltage internally - enabling single-supply operation from 1.8V to 5.5V without auxiliary rails or external components.
How does the HOLD pin function during an active SPI transaction on the AK6510CM?
When HOLD transitions low while SCK is low, the AK6510CM immediately pauses data transfer and ignores subsequent SCK edges. Upon HOLD returning high (with SCK still low), it resumes exactly where it left off - preserving internal address and instruction state without requiring retransmission.
Can the AK6510CM be used in a 1.8V-only system without level shifting?
Yes, the AK6510CM is fully specified down to 1.8V: its input thresholds scale with VCC (VIH2 = 0.8×VCC, VIL2 = 0.2×VCC), and AC timing parameters (e.g., tSKW3 = 400 ns) are guaranteed at 1.8V - enabling direct interface with 1.8V FPGAs and microcontrollers.
What memory protection mechanisms are implemented in the AK6510CM?
The AK6510CM implements three-tier protection: (1) Software-enabled block lock via BP0/BP1 bits in the status register, (2) Hardware WP pin enforcement when WPEN = 1, and (3) Write Enable/Disable state controlled by WREN/WRDI instructions - collectively preventing unintended writes during power transitions or firmware errors.
