P87LPC760 OTP MCU selection guide, introduce the features and characteristics of this product
The guide provides an overview of the P87LPC760 OTP microcontroller, including its operating frequency up to 20 MHz, voltage range of 2.7‑6.0 V, 128 B RAM, 32 B user code area, and built‑in peripherals such as two 16‑bit timers, a comparator that can form a 2‑channel ADC, a full‑duplex UART, and multiple interrupt inputs. It also describes power‑saving features, watchdog timer options, and reset mechanisms.
Additional sections list the available package types (14‑pin DIP, SOP/TSSOP), temperature ratings, supply information for different part numbers, and recommended development tools for programming and debugging the device. This manual is written in Chinese.
