Product details
Overview
DS1330ABP-70IND+ from Maxim Integrated is a 256kbit (32k × 8) nonvolatile SRAM with integrated lithium battery backup, ±5% VCC tolerance, 70ns access time, and industrial temperature support (–40°C to +85°C). It provides automatic write protection during power loss, reset signaling via RST, and daily battery health monitoring via BW - used in mission-critical data logging systems requiring guaranteed retention without external circuitry.
For engineers reviewing the DS1330ABP-70IND+ datasheet, DS1330ABP-70IND+ pinout, DS1330ABP-70IND+ application, or DS1330ABP-70IND+ equivalent, key selection considerations include its PowerCap module packaging, open-drain RST/BW outputs, VTP = 4.5V write-protection threshold, 50µA typical standby current, and requirement for separate DS9034PC+ PowerCap attachment.
Technical Context
The DS1330ABP-70IND+ implements a self-contained NV SRAM architecture with on-chip power-fail detection, lithium switch control, and battery voltage test circuitry. Its VCC monitor triggers write protection at 4.5V (VTP), asserts RST within 15µs of VCC decay, and holds reset for 200ms during power-up.
It features dual-mode timing: read cycles require CE/OE low and WE high, while write cycles activate on concurrent CE/WE low transitions. All I/Os are TTL-compatible, with open-drain RST and BW outputs requiring external pull-ups and capable of sinking 10mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 262,144-bit (32,768 × 8) fully static SRAM |
| Access Time | 70ns - guarantees deterministic read/write timing for 14MHz bus interfaces |
| VCC Operating Range | 4.75V to 5.25V - supports stable 5V ±5% systems without regulation overhead |
| Data Retention | 10 years minimum without external power - enabled by factory-sealed lithium cell and zero-battery-leakage disconnect |
| Standby Current | 50µA typical - enables ultra-low-power operation during extended backup mode |
| Temperature Range | –40°C to +85°C - qualified for industrial control, transportation, and outdoor embedded systems |
| Write Protection Threshold | VTP = 4.50V to 4.75V - initiates automatic data lock before brownout-induced corruption |
Pinout & Package
DS1330ABP-70IND+ uses a 34-pin PowerCap Module (PCM) package - a surface-mountable hybrid module requiring separate snap-on DS9034PC+ PowerCap for full functionality. The PCM integrates SRAM die, power-switching logic, and battery interface contacts; no reflow exposure to lithium cell.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A14 | Address Inputs | 15-bit address bus supporting full 32k-word addressing |
| DQ0–DQ7 | Data I/O | 8-bit bidirectional data bus with TTL-compatible levels and 10pF max capacitance |
| CE | Chip Enable | Active-low chip select; controls device activation and write cycle initiation |
| WE | Write Enable | Active-low write strobe; combined with CE to define write timing window |
| OE | Output Enable | Active-low output gate; disables DQ drivers during reads to prevent bus contention |
| RST | Reset Output | Open-drain signal asserting system reset during VCC failure and holding 200ms post-power-up |
| BW | Battery Warning | Open-drain flag activated when internal 24-hour battery test detects voltage <2.6V |
| VCC | Power Supply | +5V main supply input; powers SRAM and control logic above VTP |
| GND | Ground | Reference return path for all digital and analog circuitry |
| NC | No Connect | Unbonded pins (pins 3, 4, 34); must remain unconnected per design |
Key Features
| Feature | Design Value |
|---|---|
| Automatic Power-Fail Write Protection | Hardware-enforced data lock triggered at VTP = 4.5V, eliminating software dependency and firmware latency risk |
| Daily Battery Health Monitoring | Self-test every 24 hours using 1MΩ load for 1 second - provides early warning before capacity depletion |
| Integrated PowerCap Module Packaging | Enables surface-mount assembly without thermal damage to lithium cell; DS9034PC+ snaps on post-reflow |
| Reset Signal with Power-On Hold | RST remains active for 200ms after VCC stabilization - ensures processor reset completion before code execution |
| Lithium Cell Isolation Until First Power-Up | Factory-disconnected battery retains shelf life >10 years; electrically engages only after initial VCC application |

Equivalent & Alternatives
The following parts are listed as comparable options for similar nonvolatile SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1330YP-70IND+ | Wider VCC range (4.5V–5.5V, ±10%), lower VTP (4.25V), same pinout and PCM package | Better suited for unregulated 5V systems with higher ripple; earlier write protection may reduce usable voltage margin | Select DS1330YP-70IND+ if system VCC varies beyond ±5% or requires earlier fail-safe triggering |
| STK13C68-70I | 32k × 8 NV SRAM in SOIC-28; no integrated RST/BW; requires external battery and discrete power monitor | Lacks autonomous reset and battery warning; demands additional PCB area and design validation effort | Choose STK13C68-70I only when legacy SOIC footprint compatibility is mandatory and system-level monitoring already exists |
Compared with DS1330YP-70IND+, the DS1330ABP-70IND+ offers tighter supply regulation and higher VTP for improved noise immunity; versus STK13C68-70I, it delivers turnkey reliability with integrated monitoring and PowerCap modularity - reducing BOM count and qualification burden.

FAQ
What is the required external component for DS1330ABP-70IND+ to function as a complete nonvolatile SRAM?
The DS1330ABP-70IND+ requires a separate DS9034PC+ PowerCap to be snapped onto its 34-pin PCM base. This PowerCap contains the lithium battery and completes the nonvolatile functionality. Without the DS9034PC+, the DS1330ABP-70IND+ operates only as a volatile SRAM and cannot retain data during power loss. The DS1330ABP-70IND+ itself does not include the battery - it is designed exclusively for modular integration with this certified PowerCap.
Does DS1330ABP-70IND+ support true pin-to-pin replacement for standard 32k × 8 SRAMs?
No, DS1330ABP-70IND+ is not a direct pin-to-pin replacement for generic 32k × 8 SRAMs due to its additional RST and BW pins and different power management behavior. While it shares the core address/data/control signals (A0–A14, DQ0–DQ7, CE, WE, OE), the presence of dedicated reset and battery warning outputs - plus NC pins and PowerCap-specific footprint - requires PCB layout adaptation. System-level integration must account for open-drain RST/BW pull-ups and VCC ramp-up timing.
How does the battery monitoring feature work in DS1330ABP-70IND+?
The DS1330ABP-70IND+ performs an automated battery voltage test once every 24 hours. At each interval, it connects the internal lithium cell to a 1MΩ test resistor for one second. If voltage drops below 2.6V during that test, the BW pin is asserted and remains active until the PowerCap is replaced. BW is an open-drain output requiring an external pull-up resistor. The test resumes after each VCC power-up, even if BW is already active - allowing recovery if battery voltage recovers.
What is the significance of the "IND" suffix in DS1330ABP-70IND+?
"IND" denotes the industrial temperature grade, certifying that the DS1330ABP-70IND+ is fully specified and tested over –40°C to +85°C. This includes all DC/AC electrical characteristics, data retention, write protection thresholds, and timing parameters. Unlike commercial-grade variants, the IND version undergoes extended burn-in and screening to ensure reliability in harsh environments such as factory automation, outdoor infrastructure, and transportation systems.
Can DS1330ABP-70IND+ operate without the DS9034PC+ PowerCap installed?
Yes, DS1330ABP-70IND+ functions as a standard 32k × 8 volatile SRAM when powered and with no PowerCap attached - but it loses all nonvolatile capability. In this state, it provides 70ns access time and full read/write operation under VCC, yet offers zero data retention during power loss. The RST and BW pins remain functional (RST asserts on VCC failure, BW stays inactive), but battery monitoring and lithium switching are disabled. Full NV operation requires mechanical and electrical mating with DS9034PC+.
