Infineon Technologies CY95F634KNPMC-G-106-UNE2

Overview

CY95F634KNPMC-G-106-UNE2 from Infineon Technologies (formerly Cypress) is an 8-bit F2MC-8FX microcontroller with 60 KB Flash, 2 KB RAM, and integrated LCD controller supporting up to 40 SEG × 4 COM or 36 SEG × 8 COM. It features dual-bank Flash for concurrent read/program operations, 8/12-bit ADC (8 channels), three UART/SIO interfaces, and operates at up to 16.25 MHz machine clock frequency. Used in industrial control panels and smart appliance displays requiring low-power operation and on-chip LCD drive.

For engineers reviewing the CY95F634KNPMC-G-106-UNE2 datasheet, CY95F634KNPMC-G-106-UNE2 pinout, CY95F634KNPMC-G-106-UNE2 application, or CY95F634KNPMC-G-106-UNE2 equivalent, key selection criteria include Flash security, LCD bias resistor programmability (10 kΩ or 100 kΩ), sub-CR clock-based software watchdog timing, and standby mode flexibility (Stop/Sleep/Watch/Time-base timer).

Technical Context

The device implements the F2MC-8FX CPU core with 136 basic instructions, 1–3 byte instruction length, and 61.5 ns minimum execution time at 16.25 MHz. It supports multiple clock sources including main CR PLL (8/10/12/16 MHz ±2%), external clocks (up to 32.5 MHz), and subclocks (32.768 kHz or 100 kHz). Clock supervisor monitors both main and sub-oscillation stability.

Peripheral integration includes two 8/16-bit composite timers (configurable as PWM, input capture, or PWC), two 8/16-bit PPGs, one 16-bit reload timer, event counter, and full-duplex UART/SIO with double-buffering and NRZ format. The LCD controller provides frame-synchronized interrupt, blinking, and inverted display functions.

FAQ

What is the maximum operating frequency of the CY95F634KNPMC-G-106-UNE2?

The device supports a maximum machine clock frequency of 16.25 MHz, achievable using the main PLL clock or external clock source. At this speed, the minimum instruction execution time is 61.5 ns, and interrupt processing time is 0.6 µs - enabling responsive real-time control in display and sensor interface applications.

Does CY95F634KNPMC-G-106-UNE2 support in-system programming?

Yes - it supports serial programming via 1-wire on-chip debug interface in asynchronous mode. This allows firmware updates without removing the chip from the PCB, and the dual-bank Flash architecture permits background programming while executing code from the alternate bank.

Can the LCD controller drive custom segment layouts beyond 40×4 or 36×8?

No - the hardware LCD controller is fixed to two configurations: 40 SEG × 4 COM (160 pixels) or 36 SEG × 8 COM (288 pixels). Segment-to-pin mapping is defined in the datasheet pin assignment table and cannot be reconfigured beyond these topologies.

Is low-voltage detection (LVD) available on this part?

Yes - CY95F634KNPMC-G-106-UNE2 includes a built-in LVD circuit that generates a reset when VDD drops below a programmable threshold (typically 3.8 V or 4.2 V). This feature is absent in the L-suffix variants (e.g., MB95F778L) and confirms its suitability for battery-backed or unregulated supply applications.
