Infineon Technologies MB95F632KPMC-G-SNE2

Overview

MB95F632KPMC-G-SNE2 from Infineon Technologies (formerly Cypress) is an 8-bit Flash microcontroller based on the F2MC-8FX CPU core, featuring 8 KB Flash, 256 bytes RAM, 29 I/O ports (25 CMOS + 4 N-ch open-drain), and integrated peripherals including dual 8/16-bit composite timers, 8-channel 8/10-bit ADC, LIN-UART, I²C, UART/SIO, multi-pulse generator for DC motor control, and low-voltage detection reset. It operates up to 16.25 MHz machine clock and targets embedded control in industrial sensors and motor-driven modules.

For engineers reviewing the MB95F632KPMC-G-SNE2 datasheet, MB95F632KPMC-G-SNE2 pinout, MB95F632KPMC-G-SNE2 application, or MB95F632KPMC-G-SNE2 equivalent, key selection criteria include its LQB032 LQFP-32 package, on-chip debug via 1-wire serial interface, dual-bank Flash memory enabling concurrent read/program operations, and built-in low-voltage detection with four selectable voltage thresholds.

Technical Context

The MB95F632KPMC-G-SNE2 implements the F2MC-8FX CPU core with 136 basic instructions, 1–3 byte instruction length, and support for 16-bit arithmetic, bit manipulation, and multiplication/division. Its clock system offers flexible sourcing: main oscillation (up to 16.25 MHz), external clock (up to 32.5 MHz), main CR (4 MHz ±2%), or main CR PLL (8/10/12/16 MHz ±2%).

Peripheral integration includes a dedicated multi-pulse generator (MPG) with 16-bit PPG timer, 16-bit reload timer, event counter, and waveform sequencer for precise DC motor commutation; plus LIN-UART supporting both master and slave roles with full-duplex double-buffered transfer and programmable baud rates.

FAQ

Does MB95F632KPMC-G-SNE2 support in-system programming via its on-chip debug interface?

Yes. The device supports asynchronous serial programming using a single-wire debug (SWD) interface on Pin P12 (DBG/EC0). This enables firmware updates and debugging without removing the chip from the board, provided VCC, VSS, and the debug pin are accessible per Infineon's hardware manual section 25.

What is the maximum operating frequency of the main oscillator circuit?

The main oscillator supports up to 16.25 MHz machine clock frequency when driven by an external crystal or ceramic resonator. At this frequency, minimum instruction execution time is 61.5 ns, and interrupt processing time is 0.6 µs - verified under recommended operating conditions (VDD = 3.0–5.5 V, TA = –40 to +85 °C).

Can the 8/10-bit ADC operate concurrently with CPU execution?

Yes. The ADC features autonomous conversion triggered by timer events or software start, with results stored directly in dedicated registers. Conversion completes in 13 µs (10-bit, fADCLK = 1 MHz), and the CPU can continue executing instructions or enter low-power modes during acquisition - confirmed in Section 18.5 of datasheet 002-04627.

Is the low-voltage detection function available on all CY95F632 variants?

No. Low-voltage detection reset is exclusive to the "K" suffix variants (e.g., MB95F632KPMC-G-SNE2), not present in "H" variants like CY95F632H. Four detection/release voltage combinations (e.g., 2.7 V/2.8 V, 3.3 V/3.4 V) are selectable via dedicated control bits in the LVD register - documented in Section 3.1 and electrical characteristics Table 18.2.
