Infineon Technologies CY95F778JNPMC1-G-UNE2

Overview

CY95F778JNPMC1-G-UNE2 from Infineon Technologies (formerly Cypress) is an 8-bit F2MC-8FX microcontroller with 60 KB flash, 2 KB RAM, integrated LCD controller (32 SEG × 4 COM or 28 SEG × 8 COM), 8/12-bit ADC (8 channels), and three UART/SIO interfaces. It operates at up to 16.25 MHz machine clock using main PLL or external clock, and supports four low-power standby modes including Watch and Time-base timer modes - deployed in industrial panel meters and portable instrumentation.

For engineers reviewing the CY95F778JNPMC1-G-UNE2 datasheet, CY95F778JNPMC1-G-UNE2 pinout, CY95F778JNPMC1-G-UNE2 application, or CY95F778JNPMC1-G-UNE2 equivalent, key selection criteria include verified LCD drive capability (28–32 SEG), dual-bank Flash for concurrent read/erase, LVD reset support, 8-channel ADC resolution selectability (8/12-bit), and I²C + 3× UART/SIO peripheral integration.

Technical Context

This MCU 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 integrates a clock supervisor counter monitoring both main and subclock oscillation stability, plus hardware/software watchdog timers with configurable timeout sources including sub-CR clock.

The peripheral set includes two 8/16-bit composite timers (supporting PWM, input capture, PWC), one 16-bit reload timer, one event counter, one time-base timer, one watch counter (with 125 ms–1 s selectable clock sources), and one comparator. All timers and ADCs are directly memory-mapped and interrupt-capable with priority control.

FAQ

Does CY95F778JNPMC1-G-UNE2 support in-system programming via UART?

Yes - the device supports asynchronous serial programming through UART0 using the on-chip bootloader. The process requires no external programmer; only a 3.3 V–5.5 V supply, UART connection, and valid boot sequence (including checksum verification) as defined in Section 25 of datasheet 002-09307 Rev. *F. No external high-voltage signal is needed.

What LCD bias configuration options are available on this MCU?

The LCDC supports software-selectable internal divider resistors of 10 kΩ or 100 kΩ for LCD bias generation, eliminating external resistor networks. Bias voltage is derived from VDD and adjusted automatically based on selected SEG/COM count and duty ratio - validated for 32 SEG × 4 COM and 28 SEG × 8 COM configurations per datasheet Section 1.2.

Is the low-voltage detection (LVD) function available on all CY95F778J variants?

Yes - LVD reset is implemented on all "J" suffix variants (CY95F774J, CY95F776J, CY95F778J), including CY95F778JNPMC1-G-UNE2. It provides six user-selectable trip points between 2.7 V and 4.5 V (±2%), with dedicated interrupt and reset output - confirmed in Electrical Characteristics Table 22.3 of datasheet 002-09307 Rev. *F.

Can the 8/12-bit ADC operate concurrently with LCD refresh?

Yes - the ADC and LCD controller operate independently using separate clock domains and DMA-capable registers. Sampling can be triggered by timer overflow or software while the LCDC maintains frame-synchronized refresh at up to 120 Hz, with no hardware conflict - verified in I/O Map (Section 19) and ADC Timing Diagrams (Section 22.5) of the datasheet.
