Product details
Overview
AT28C010-15JC from Atmel is a 1-Mbit (128K × 8) paged parallel EEPROM with JEDEC-standard byte-wide pinout, 150 ns read access time, 10 ms maximum page write cycle, and CMOS/TTL-compatible I/O. It operates on single 5V ±10% supply and supports hardware/software data protection for embedded firmware storage in industrial control systems.
For engineers reviewing the AT28C010-15JC datasheet, AT28C010-15JC pinout, AT28C010-15JC application, or AT28C010-15JC equivalent, key selection criteria include page-write timing (≤10 ms), DATA polling support via I/O7, 10⁴/10⁵ endurance cycles, 10-year data retention, and PLCC-32 packaging with industrial temperature range (-40°C to +85°C).
Technical Context
The AT28C010-15JC implements a 128-byte internal page register that latches address and data during write initiation, freeing the bus for concurrent operations. Its internal control timer automates programming after latch completion, eliminating external timing circuitry.
Write detection uses dual methods: DATA polling (I/O7 complement-to-data toggle) and TOGGLE BIT (I/O6 state alternation), both functional across full operating voltage and temperature ranges. Hardware protection includes VCC sense (<3.8 V inhibit), 5 ms power-on delay, and noise filtering (15 ns pulse rejection on WE/CE).

Pinout & Package
AT28C010-15JC is packaged in a 32-lead Plastic J-leaded Chip Carrier (PLCC-32) with JEDEC MS-016AE outline. Pin 1 is designated "Don't Connect" (DC) per manufacturer specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar paged parallel EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT28C010-15JI | Same die and timing, but rated for industrial temperature (-40°C to +85°C) and supplied in PLCC-32 package | Identical functionality; differs only in temperature screening and part marking | Select AT28C010-15JI when full industrial temperature compliance is required and PLCC-32 is acceptable |
| MX28LV160CBTI-15G | 16-Mbit capacity, 3V core, requires level-shifting for 5V systems; lacks hardware VCC-sense protection | Higher density but incompatible voltage domain and reduced write-protection robustness | Choose MX28LV160CBTI-15G only if migrating to 3V architecture and accepting trade-offs in power-supply immunity |
Compared with AT28C010-15JC, AT28C010-15JI offers identical electrical behavior with guaranteed industrial temperature operation, while MX28LV160CBTI-15G provides greater density at the cost of 5V compatibility and hardware-level write safety - making AT28C010-15JC optimal for legacy 5V industrial designs requiring proven reliability.

FAQ
What is the maximum page write time for AT28C010-15JC?
The AT28C010-15JC has a maximum page write cycle time of 10 ms, as specified in the AC characteristics table. This value applies to all 1–128 byte writes within a single page (defined by A7–A16). The internal control timer ensures consistent timing regardless of ambient temperature or supply voltage within rated limits, and this parameter is fully characterized - not just typical.
Does AT28C010-15JC support both hardware and software write protection?
Yes, AT28C010-15JC implements dual-layer protection: hardware features include VCC sensing (<3.8 V inhibit), 5 ms power-on delay, and 15 ns noise filtering on WE/CE inputs; software protection uses a user-configurable 3-byte command sequence (AAh/55h/A0h) to enable/disable write blocking. Both mechanisms operate independently and are active simultaneously unless disabled via the software sequence.
What package type is used for AT28C010-15JC?
AT28C010-15JC uses a 32-lead Plastic J-leaded Chip Carrier (PLCC-32) package per JEDEC MS-016AE standard. Pin 1 is explicitly marked "Don't Connect" (DC) in the datasheet and must remain unconnected. This surface-mount package supports reflow soldering and provides mechanical robustness for industrial board assembly.
Can AT28C010-15JC be used in place of AT28C010-12JC?
AT28C010-15JC is functionally compatible with AT28C010-12JC but has a slower maximum read access time (150 ns vs. 120 ns). Systems designed for the -12JC variant may experience timing violations if operated at maximum bus frequency; however, AT28C010-15JC remains fully compatible in applications with ≥150 ns address-to-data timing margins or those using wait-state insertion.
How is write completion detected on AT28C010-15JC?
AT28C010-15JC supports two independent write completion detection methods: DATA polling monitors I/O7 (complement-to-data until completion, then true data), and TOGGLE BIT monitors I/O6 (toggles between 0/1 during write, stabilizes afterward). Both methods are valid at any point during the write cycle and require no additional hardware - enabling efficient polling loops or interrupt-driven firmware design.
