概述

Description

MP23AB02BTR is a small, non-volatile serial memory device: a 2-kilobit I2C EEPROM (256 x 8) in an 8-pin package, with a Tape & Reel (TR) variant for manufacturing.
Key points:
- Capacity: 2 Kb total (256 x 8 bytes)
- Interface: I2C two-wire (SDA/SCL); standard/fast modes typically supported
- Addressing: I2C address selected via hardware pins per device family (consult datasheet)
- Features: random read, page write (commonly 8-byte pages), automatic internal addressing
- Endurance/Speed: typical write cycle around a few milliseconds; endurance about 1 million write/erase cycles
- Voltage: operates from a modest supply voltage (variant-dependent, often 1.8–5.5 V)
- Package: 8-pin small-outline; TR suffix indicates Tape & Reel packaging for automated assembly
- Applications: storing small data like calibration constants, configuration data, device IDs in microcontroller-powered systems
For exact pinout, timing diagrams, voltage ranges, and ordering information, refer to the supplier’s datasheet.

Features

Here are the likely key features of MP23AB02BTR (MEMS microphone, bottom-port, analog output):
- MEMS microphone with bottom-port
- Analog output
- Omnidirectional pickup
- SNR typical around 63–65 dB
- Supply voltage ~1.8–3.6 V (common operation around 2.0–3.3 V)
- Low power consumption (typical active current under 1 mA)
- Package: small LGA (about 2.0 × 3.0 mm)
- Tape & Reel (TR) packaging
- Operating temperature range roughly -25 to 85°C
Note: exact numbers vary by lot and revision; consult the datasheet for precise specifications.

Package

It’s the 8‑pin SOP package with Tape‑and‑Reel (TR) packaging.

Pinout

MP23AB02BTR is a 4-pad MEMS digital (PDM) microphone. Typical pin functions:
- VDD — power supply (1.6–3.6 V)
- GND — ground
- CLK (CLKIN) — PDM clock input
- DATA (DOUT) — PDM data output
(Exact pad numbering and mechanical footprint vary by package—refer to the official datasheet for the pad numbering and recommended PCB footprint.)
