The SST39SF040-55-4C-WHE is a 4 Mbit CMOS Multi-Purpose Flash memory device utilizing SST's SuperFlash technology. It operates with a single power supply voltage of 4.5-5.5V and conforms to JEDEC standard pinouts for x8 memories. The device features a fast read access time of 55 ns and supports sector erase capabilities with uniform 4 KByte sectors. Typical endurance is rated at 100,000 cycles, and data retention exceeds 100 years. The memory supports automatic write timing and includes end-of-write detection through Toggle Bit and Data# Polling. It has low power consumption characteristics, with an active current of 10 mA and standby current of 30 µA at 14 MHz. The SST39SF040-55-4C-WHE is available in multiple package options, including 32-lead PLCC, 32-lead TSOP, and 32-pin PDIP, and is RoHS compliant. This device is suitable for applications requiring reliable and efficient data storage and updating.
