Product Overview
The IS42S32200L-6BLI is a low-voltage 64Mb SDRAM from ISSI, built with 4-bank 2M×32 architecture. It runs at 166MHz (6ns tCK, 5.4ns tAC) with 3.0~3.6V supply, supporting programmable burst and CAS latency. Industrial-grade (-40°C~+85°C) 90-ball TFBGA package, NRND obsolete with limited stock, fit for legacy industrial, communication and automotive embedded devices.
Core Advantages
Ultra-Wide 32-Bit Data Interface
32-bit parallel bus delivers high throughput, single chip meets system bandwidth demand.
166MHz High-Speed Operation
6ns cycle & 5.4ns access time eliminates data delay for embedded processors.
Industrial Wide Temperature Support
-40℃~+85℃ stable operation, separate from commercial 0~70℃ -6BL version.
Efficient 4-Bank Architecture
Interleaved bank design hides activate/precharge cycles to boost continuous read/write efficiency.

Frequently Asked Questions
Q1: What do suffix codes -6BLI mean?
A: -6: 6ns speed grade, max 166MHz, tAC=5.4ns; BL: lead-free 90-ball TFBGA package; I: industrial grade (-40℃~+85℃), commercial version is -6BL (0~70℃).
Q2: What’s the benefit of 32-bit wide data bus?
A: It delivers higher bandwidth than ×8/×16 SDRAM. One single chip outputs full 32-bit data per clock, reducing PCB component count and layout area.
Q3: How often do I need to run refresh command?
A: Send 4K auto-refresh command every 64ms to keep data stable under full industrial temperature range.
Q4: Can this chip connect directly to 5V MCU?
A: No. Its core and IO only support 3.0V~3.6V supply. Level shift chips are required when interfacing with 5V logic, otherwise the chip will be damaged.
Q5: Is IS42S32200L-6BLI still in production?
A: This part is NRND (No Longer Manufactured). Only limited leftover stock available. New projects need to switch to compatible alternatives.
Q6: What compatible replacement models can I use?
A: 1. IS42S32200L-7BLI: 143MHz industrial grade, pin-to-pin fully compatible, wider stock supply; 2. IS45S32200-6BLI: upgraded low-power SDRAM with same footprint; 3. Micron MT48LC32M32-6A IT: cross-brand industrial 32-bit 64Mb SDRAM, same electrical specs.
Q7: Are there risks buying obsolete NRND chips?
A: Stock is limited, batch consistency varies. We test all inventory before delivery; for mass long-term projects, replacement models are strongly recommended to avoid stock outage risks.
Q8: Do replacement chips need PCB redesign?
A: The recommended alternative models share identical 90-ball TFBGA footprint, same voltage and bus definition. No PCB layout modification is needed for direct drop-in replacement.
Q9: Can I get free samples for alternative models?
A: Yes, we provide small free samples of all compatible replacement parts for customer testing. Submit your sample demand via the inquiry form with project details.
