Zhongwei Aixin: New Product Launch—High Reliability, Full-Mapping 32 KB Flash ROM Touch-Enabled 8051 Microcontroller——AiP8F3232
Introduction
Zhongwei Aixin has launched the AiP8F3232—a highly reliable, fully mapped 32 KB Flash ROM touch-enabled 8051 microcontroller. The AiP8F3232 introduces a game-changing “one-stop” solution: one single chip integrates touch sensing, display control, and general-purpose control, enabling you to meet system requirements that previously demanded three or even more discrete chips. This all-in-one smart-control chip empowers you to deliver feature-rich, smoothly responsive product designs with a more streamlined architecture, effectively reducing costs and accelerating time-to-market.

Any Port Mapping · Freedom in PCB Design
Intelligent Priority Management & Systematic Development Tool
When multiple output functions are mapped to the same pin, the hardware automatically selects the highest-priority function for output according to the default priority, thereby preventing conflicting inputs. The input function supports multiplexing, offering flexible and reliable operation.
UART, I2C, and PWM O/1/2 function ports support arbitrary I/O mapping.
The six PWM channels (PWMA–F) of the advanced timer T5 can be freely switched among PO, P1, P4, and P5, completely eliminating pin conflict issues.
Easily reassign peripheral pins using dedicated mapping registers (such as AFCR TX1, AFCR SCLAFCR, and PWMO), doubling development efficiency.
High-performance touch solutions with a robust development ecosystem
Touch-based Host Computer Debugging Software & Touch Control DEMO Board
Real-time monitoring of count value changes for each channel, with intuitive adjustment of sensitivity thresholds and filtering parameters, eliminates reliance on subjective feel during touch calibration and enables rapid achievement of mass-production readiness.
Ready-to-use touch demo boards are available, supporting applications such as waterproofing and low-power wake-up. Developers can achieve plug-and-play functionality and complete prototype validation in just a few hours.
Up to 25 touch-key channels
CTC (charge-transfer) architecture, high sensitivity, strong anti-interference—requires only an external capacitor on the CAP pin (P07).
16-bit counter with adjustable charge/discharge clock frequency, 4-level selectable comparator reference voltage, independent touch oscillator, automatic/manual frequency hopping, and enhanced resilience to harsh environments.
