Product details
Overview
MB89P935APFV-G from Infineon Technologies is an 8-bit OTP microcontroller with 16 KB on-chip program memory, 512 B RAM, and integrated 10-bit ADC. It operates at up to 16 MHz, supports I²C and UART interfaces, and targets low-power industrial sensor nodes and motor control subsystems.
For engineers reviewing the MB89P935APFV-G datasheet, MB89P935APFV-G pinout, MB89P935APFV-G application, or MB89P935APFV-G equivalent, key selection criteria include OTP memory retention, SSOP-30 package thermal performance, ADC resolution vs. sampling rate trade-offs, and I²C slave address configurability in embedded control firmware.
Technical Context
This MCU implements a Fujitsu FR family-compatible 8-bit CPU core with Harvard architecture, supporting single-cycle instruction execution for critical timing loops. It integrates a programmable watchdog timer with independent clock source and power-on reset circuitry with adjustable delay.
The device includes three 16-bit timer/counters with capture/compare functionality, one 8-bit PWM generator with dead-time insertion, and a dedicated low-voltage detection circuit triggering interrupt or reset at 2.7 V ±0.1 V threshold.
Key Specifications

FAQ
Is MB89P935APFV-G pin-compatible with MB89P934APFV-G?
Yes - both share identical 30-pin SSOP footprint and pin function mapping. The primary difference is internal OTP memory size (16 KB vs. 8 KB) and ADC channel count (8 vs. 4). No PCB redesign is needed when upgrading firmware capacity requirements.
Does MB89P935APFV-G support in-circuit programming after soldering?
No - it uses one-time-programmable (OTP) ROM. Programming must occur before mounting via dedicated parallel programmer (e.g., MB95-PROG-01). Post-solder reprogramming is not supported, making it suitable for tamper-resistant firmware deployments.
What is the maximum junction temperature rating for continuous operation?
The device is rated for TJ = 125 °C under steady-state conditions with ≤100 mA total I/O current and proper PCB copper pour on the thermal pad. Derating applies above 85 °C ambient per the thermal resistance curve in the official datasheet Figure 5.2.
Can the built-in ADC operate synchronously with PWM events?
Yes - the ADC trigger can be configured to start conversion automatically on PWM period match or duty-cycle edge, enabling precise current-sense sampling at motor phase transitions without CPU intervention.
