Intellisense Microelectronics Ltd. Programmable CMOS Optical Sensor IC ISL700D_SRE

1. Product overview • The lSL700DE is a highly-integrated CMOs photoelectric sensor lC designed forhigh-speed, programmable diffuse-reflective sensing. lt integrates an LED/laser emitter driver, a transimpedance/analo g chain with sample-and-hold (S/H), and configuration registers with CRC guard. • lSL700DE outputs an analog voltage at SH_OUT that represents the averaged reflective signal (two emission periods by default)enabling microcontrollers with ADC to implement dynamic range adjustment, anti-interference algorithm, thresholds setting, teach-in etc advanced function in compact sensors. • Fabricated in an AEC-Q100-qualified foundry, ISL700DE delivers long term stability and reliability • An external clock can be used to adjust the emitter frequency, pulse width, and duty cycle; multiple sensors can operate side-by-side via frequency programming or sensor to sensor synchronization. Programmable parameters include LED drive voltage, multi-stage gain, internal clock selection, and mode settings. Short-circuit protection,start-up delay, and error reporting(STS) are integrated. 2. Key Featurese • Analog output for microcontroller ADC; SW_OUT output the in-phase output pulse signal synchronized with PLS(emitter). • Programmable LED driver voltage (0-255, wide 0-5 V drive range). • Programmable multi-stage gain: (4-bit 32K-16*32K I-V)x(4-bit 2-32)x(4-bit 2-32)x(10-bit 0.9-3.6)for large dynamic range. • External clock options (ext_slyclk, sxt_clk_hf) to tune emitter frequency, pulse width(Tw), and period (Tp). • Fast response:< 20 μs (application dependent). • Ambient/interference mitigation workflows: CLOSE_PLS (disable emission) to probe external light; SW_OUT phase check. • CRC-protected configuration with STS pin to flag register integrity. • Operating temperature: -40℃ to +85℃; robust ESD tolerance (HMB). 3.
