Questions buyers ask
- Can M65831 replace M65831?
- M65831 is I-CORE's functional equivalent of M65831 in the same SOP-24 package. Standard parts in this family share the industry pinout, but please compare both datasheets — supply range, timing and absolute maximum ratings — before design-in.
- What is the supply voltage and temperature range of M65831?
- Supply: See datasheet. Operating temperature: See datasheet. See the datasheet for full electrical characteristics.
- Is M65831 in stock, and can I get a free sample?
- Yes, it is held in stock in Shenzhen. Free samples are available for evaluation, with shipping paid by us. For production orders, SMD parts can be ordered from 1 pc and DIP parts ship in full tubes; orders ship within 2–3 business days after payment.
- Is it original I-CORE product?
- Yes. We supply factory-original I-CORE (Wuxi I-CORE Electronics) parts in sealed reels and tubes. Our ISO 9001, ISO 14001 and ISO 45001 certificates are shown on the home page; RoHS and REACH test reports are available on request.
Datasheet highlights
From the I-CORE English datasheet M65831 (revision 2026-03-B5). The full datasheet PDF is linked above.
General description
Package form：SOP24 or The M65831 is an IC developed for producing echo effects added to voice signals picked up by microphone for karaoke applications. The IC has the largest memory among the digital delay series. As it’s design is aimed at high performance, it is best suited to provide radio cassette tape recorders and miniature unit audio system with quality echo function.
Key features
- Built-in input / output filters, A-D and D-A converters, and memory realize a delay system with
- only a single chip
- Capable of composing low-noise and low-distortion delay system at low cost by ADM system
- (No=-92dB typ, THD=0.5% typ)
- Control mode selections available from 2 kinds: easy mode using parallel data and
- microcomputer mode using serial data
- Sleep mode can be selected to stop IC functions
- Built-in automatic reset circuit
