Infineon Technologies MB95F334KPMC-G-SNE2

Overview

MB95F334KPMC-G-SNE2 from Cypress Semiconductor is an 8-bit F2MC-8FX microcontroller with 20 KB Flash, 1008 bytes RAM, 29 I/O ports (25 CMOS + 4 N-ch open-drain), and integrated LIN-UART, I²C, dual UART/SIO, 8/10-bit 8-channel ADC, and multi-pulse generator for DC motor control. It operates at up to 16.25 MHz machine clock using external clock input and supports four low-power standby modes.

For engineers reviewing the MB95F334KPMC-G-SNE2 datasheet, MB95F334KPMC-G-SNE2 pinout, MB95F334KPMC-G-SNE2 application, or MB95F334KPMC-G-SNE2 equivalent, key selection criteria include LIN master/slave capability, dual-bank Flash security, on-chip debug via 1-wire serial interface, and PPG-based PWM waveform sequencing for embedded motor control systems.

Technical Context

The MB95F334KPMC-G-SNE2 implements the F2MC-8FX CPU core with 136 instructions, 1–3 byte encoding, and hardware support for 16-bit arithmetic, multiplication/division, and bit manipulation. Its interrupt latency is 0.6 µs at 16.25 MHz, enabling deterministic real-time response in motor and sensor interfaces.

Peripheral integration includes a dedicated multi-pulse generator (MPG) with 16-bit PPG timer, 16-bit reload timer, event counter, and waveform sequencer - all synchronized to generate precise multi-phase drive signals. The LIN-UART channel supports both asynchronous (UART) and synchronous (SIO) modes with full-duplex double buffering and programmable baud rates.

The MB95330H Series targets cost-sensitive, real-time embedded control applications requiring LIN connectivity, motor drive peripherals, and secure Flash - especially in automotive sub-systems and industrial automation where peripheral consolidation reduces board area and bill-of-materials.

FAQ

Does MB95F334KPMC-G-SNE2 support LIN 2.2 protocol natively?

Yes - the integrated LIN-UART peripheral supports LIN 2.2 frame formatting, including identifier filtering, checksum calculation (classic/enhanced), and automatic sync-break detection. It operates as either master or slave without external protocol stack software, reducing CPU load and latency in automotive networks.

What is the maximum operating frequency of the PPG timers in PWM mode?

The PPG timers operate at up to 16.25 MHz machine clock frequency. In 16-bit PWM mode with prescaler = 1, the minimum PWM period is 61.5 ns per count, enabling output frequencies up to ~16.25 MHz for single-cycle toggling or ~8.125 MHz for standard complementary PWM generation.

Can the on-chip debug interface be used in all low-power modes?

No - the 1-wire debug interface remains active only in normal and sleep modes. It is disabled in stop, watch, and time-base timer modes to minimize leakage current. Debug access requires waking the device first via external interrupt or reset before resuming serial communication.

Is Flash memory security enabled by default after programming?

No - Flash security must be explicitly enabled via the Flash security bit in the option byte configuration. Once set, the security lock prevents external readout and debug access; unlocking requires full chip erase. This behavior is confirmed in Cypress Document 002-07522 Rev. *A, Section "Flash Memory Security Function".
