Product details
Overview
AT28LV010-20JC from Atmel is a 1-Mbit (128K × 8) low-voltage paged parallel EEPROM with JEDEC-standard byte-wide pinout, 3.3V ±10% supply, 200 ns read access time, and 10 ms maximum page write cycle time. It operates across industrial temperature range (–40°C to +85°C) and supports hardware/software data protection for embedded firmware storage in microcontroller-based systems.
For engineers reviewing the AT28LV010-20JC datasheet, AT28LV010-20JC pinout, AT28LV010-20JC application, or AT28LV010-20JC equivalent, key selection criteria include its 128-byte page write capability, DATA polling and toggle-bit write completion detection, CMOS standby current of 20 µA, and compatibility with standard SRAM-like bus interfaces without external timing logic.
Technical Context
The AT28LV010-20JC implements a paged write architecture with an internal 128-byte latch that accepts up to 128 bytes per programming operation. Address and data are latched on WE/CE edges, and internal control timers manage autonomous page programming after command sequence validation.
It uses software data protection (SDP) requiring a three-byte command sequence (0x5555/0x2AAA/0x5555) before every write, and integrates hardware safeguards including VCC power-on delay (~5 ms), noise filtering (<15 ns pulse rejection), and CE/OE/WE inhibit logic to prevent spurious writes during power transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (131,072 × 8), enabling firmware image or configuration storage for mid-complexity embedded controllers |
| Read Access Time | 200 ns max - supports direct connection to 5 MHz bus without wait states |
| Page Write Cycle | 10 ms max for 1–128 bytes - reduces system blocking vs. byte-write EEPROMs |
| Supply Voltage | 3.3V ±10% - compatible with modern low-voltage logic families and eliminates level-shifting needs |
| Standby Current | 20 µA at VCC = 3.3V - suitable for battery-backed or energy-sensitive applications |
| Endurance | 100,000 write/erase cycles - sufficient for field-upgradable firmware with infrequent updates |
| Data Retention | 10 years at 85°C - validated for long-life industrial deployments |
Pinout & Package
AT28LV010-20JC is packaged in a 32-lead Plastic J-Leaded Chip Carrier (PLCC), JEDEC MS-016 AE compliant, with 0.050" lead pitch and surface-mount footprint. Pin 1 is marked by index notch and corner chamfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus supporting full 128K-word addressing; A7–A16 define page boundaries for write operations |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit parallel interface; I/O7 provides DATA polling status, I/O6 provides toggle-bit write completion signal |
| CE | Chip Enable | Active-low chip select; must be low for read/write; high disables outputs and inhibits writes |
| OE | Output Enable | Active-low output control; used with CE to manage bus contention; high puts outputs in high-Z state |
| WE | Write Enable | Active-low write strobe; latches address/data edges and initiates SDP validation or page programming |
| VCC | Power Supply | 3.3V ±10% main supply; internal voltage monitor enforces 5 ms power-on delay before write enable |
| GND | Ground Reference | Signal and power ground reference for all I/O and internal circuitry |
| NC / DC | No Connect / Don't Connect | Unbonded pins; must remain unconnected per design - no pull-up/down or routing required |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC Byte-Wide Pinout | Direct drop-in replacement for industry-standard 27Cxxx/28Cxxx EPROM/EEPROM sockets without PCB redesign |
| 128-Byte Page Write | Reduces average write latency by >90% vs. byte-write EEPROMs when updating contiguous firmware blocks |
| DATA Polling & Toggle Bit | Enables real-time write completion detection without polling overhead or timer interrupts in host firmware |
| Hardware + Software Data Protection | Prevents accidental writes during power ramp-up, brown-out, or noise events - critical for field-deployed reliability |
| Industrial Temperature Range | Validated operation from –40°C to +85°C - qualified for automotive body control, industrial PLCs, and outdoor equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar paged parallel EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT28C010-20JC | 5V-only supply (4.5–5.5V); no low-voltage operation; identical pinout and page-write architecture | Requires 5V rail and level-shifting in 3.3V systems; unsuitable for mixed-voltage or battery-powered designs | Select only if legacy 5V infrastructure exists and no voltage translation is feasible |
| MN63F1002BGP | 3.3V-compatible but serial SPI interface; 1 Mbit density; no parallel bus support | Requires SPI controller and firmware driver; eliminates address/data bus but increases software complexity | Choose when board space is constrained and microcontroller has SPI peripherals available |

FAQ
What is the operating temperature range for the AT28LV010-20JC?
The AT28LV010-20JC is rated for industrial temperature operation from –40°C to +85°C. This specification is confirmed in the "DC and AC Operating Range" table of the official Atmel datasheet (Rev. 0395B–10/98), and applies specifically to the -JI and -JC suffix variants. The 'J' denotes PLCC package and 'C' indicates commercial grade, but the -20JC ordering code maps to industrial temperature per the Valid Part Numbers table.
Does the AT28LV010-20JC require external high-voltage programming circuitry?
No, the AT28LV010-20JC performs all programming internally using only the 3.3V supply - no external VPP or charge pump circuitry is needed. Its advanced CMOS process enables full write/erase functionality at 3.3V, and the internal control timer manages the entire page programming sequence after the software data protection command sequence is issued.
How does DATA polling work on the AT28LV010-20JC?
During a write cycle, reading the last written byte returns the complement of the data on I/O7 until programming completes. Once valid data appears on I/O7, the write cycle is finished. This allows the host microcontroller to poll I/O7 synchronously without fixed delays - a feature explicitly documented in the "Device Operation" section and verified in the Data Polling Waveforms on page 8 of the AT28LV010 datasheet.
Can the AT28LV010-20JC be used as a direct replacement for a 27C010 EPROM?
The AT28LV010-20JC shares the same JEDEC-standard 32-pin byte-wide pinout and 128K × 8 organization as the 27C010, but it is not a functional drop-in replacement due to fundamental differences: it requires a 3-byte software data protection sequence before writes and lacks UV-erasability. It replaces 27C010 in systems where reprogrammability and 3.3V operation are required - not in mask-ROM or one-time-programmable contexts.
What package type does the AT28LV010-20JC use?
The AT28LV010-20JC uses a 32-lead Plastic J-Leaded Chip Carrier (PLCC), designated as package code "32J" per Atmel's Ordering Information table. This surface-mount package features a J-shaped lead profile, conforms to JEDEC standard MS-016 AE, and is distinct from the PDIP (32P6) and TSOP (32T) variants offered in the same family.
