Product details
Overview
MB89P935BPFV-G-BI8E1 from Infineon Technologies is an 8-bit OTP microcontroller with 16 KB on-chip program memory, 512-byte 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 MB89P935BPFV-G-BI8E1 datasheet, MB89P935BPFV-G-BI8E1 pinout, MB89P935BPFV-G-BI8E1 application, or MB89P935BPFV-G-BI8E1 equivalent, key selection criteria include OTP code security, SSOP-30 package compatibility, ADC resolution and sampling rate, interrupt latency, and I²C master/slave timing compliance.
Technical Context
This MCU implements a Harvard architecture with separate instruction and data buses, enabling single-cycle instruction execution for critical real-time tasks. It integrates a watchdog timer with independent clock source and power-on reset circuitry with programmable delay.
The on-chip 10-bit ADC features 8 selectable input channels, configurable sample-and-hold timing, and automatic channel sequencing triggered by timer overflow or external event. Internal oscillator supports 1–16 MHz operation with ±2% accuracy over temperature and voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | 8-bit F²MC-8FX core with 16 MHz max clock; enables deterministic 1-cycle instruction fetch/execute for time-critical control loops. |
| Program Memory | 16 KB OTP ROM; provides non-volatile, tamper-resistant firmware storage without external flash or EEPROM dependency. |
| Data RAM | 512 bytes SRAM; sufficient for stack, variables, and small buffers in sensor acquisition and PWM modulation routines. |
| ADC Resolution | 10-bit SAR ADC; delivers 1 LSB = 4.88 mV @ 5 V reference, supporting precise analog signal digitization in motor current sensing. |
| Communication | I²C (up to 400 kHz) + UART (asynchronous, full-duplex); enables direct connection to temperature sensors and host controllers without level-shifting. |
| Package | 30-pin SSOP (7.6 × 10.2 mm, 0.635 mm pitch); compatible with standard surface-mount reflow profiles and automated optical inspection. |
Pinout & Package
MB89P935BPFV-G-BI8E1 is housed in a 30-pin Shrink Small Outline Package (SSOP) with 0.635 mm lead pitch and exposed thermal pad. The package meets JEDEC MS-012AC standards and supports thermal dissipation up to 1.2 W under forced-air convection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dual 5 V supply pins with dedicated decoupling paths reduce noise coupling into analog and digital domains. |
| XTAL1/XTAL2 | Crystal oscillator inputs | Supports 1–16 MHz parallel-resonant crystals; internal load capacitors eliminate need for external caps in basic configurations. |
| AD0–AD7 | Analog input channels | Eight multiplexed ADC inputs; AD0–AD3 support differential mode for noise-rejecting current sensing applications. |
| SCL/SDA | I²C bus interface | Open-drain outputs with internal pull-up enable direct connection to 3.3 V or 5 V I²C slaves without external resistors. |
| TXD/RXD | UART serial interface | Full-duplex asynchronous communication; RXD includes noise filter to suppress EMI-induced false start bits. |
Key Features
| Feature | Design Value |
|---|---|
| OTP Program Memory Security | Read-protection lock bit prevents firmware extraction via external programming tools, meeting basic IP protection requirements. |
| Low-Power Stop Mode | Consumes ≤1.2 µA at 25 °C with RTC active; extends battery life in wireless sensor transmitters between wake-up intervals. |
| Hardware Watchdog Timer | Independent RC oscillator ensures reliable system recovery even if main clock fails or software hangs. |

FAQ
Is MB89P935BPFV-G-BI8E1 pin-compatible with MB89P935BPFV-G-BI8E2?
Yes, MB89P935BPFV-G-BI8E1 and MB89P935BPFV-G-BI8E2 share identical pinout, package dimensions, and electrical characteristics. They differ only in OTP mask version and firmware content, making them mechanically and electrically interchangeable on the same PCB.
Does this MCU support in-circuit programming after soldering?
No. MB89P935BPFV-G-BI8E1 uses one-time-programmable (OTP) ROM. Firmware must be programmed before mounting, and no debug interface (e.g., SWD, JTAG) or bootloader is provided for post-solder programming or field updates.
What is the maximum operating ambient temperature for continuous operation?
The device is rated for continuous operation from –40 °C to +85 °C ambient temperature. Thermal derating is not required within this range when mounted on a standard FR-4 PCB with 2 oz copper and minimal copper pour around the SSOP-30 footprint.
Can the internal oscillator replace an external crystal for UART timing?
The internal oscillator achieves ±2% accuracy over voltage and temperature, which exceeds the ±3% tolerance required for 9600 bps UART communication. However, for 115200 bps or higher baud rates, an external crystal is recommended to ensure reliable frame synchronization.
