Infineon Technologies CY95F778EPMC2-G-UNE2

Overview

CY95F778EPMC2-G-UNE2 from Infineon Technologies (formerly Cypress) is an 8-bit Flash microcontroller based on the F2MC-8FX CPU core, featuring 60 KB on-chip Flash, 2 KB RAM, 59 I/O ports (55 CMOS + 4 N-ch open-drain), and integrated LCD controller supporting up to 28 SEG × 8 COM or 32 SEG × 4 COM. It operates at up to 16.25 MHz machine clock with selectable clock sources including main CR PLL (16 MHz ±2%) and suboscillation (32.768 kHz), and targets embedded control in appliance displays and industrial HMI panels.

For engineers reviewing the CY95F778EPMC2-G-UNE2 datasheet, CY95F778EPMC2-G-UNE2 pinout, CY95F778EPMC2-G-UNE2 application, or CY95F778EPMC2-G-UNE2 equivalent, key selection criteria include its dual-bank Flash architecture enabling concurrent read/erase, built-in low-voltage detection (LVD), hardware/software watchdog timers, and 8/12-bit ADC with 8 channels - all validated for operation across -40°C to +85°C industrial temperature range.

Technical Context

The CY95F778EPMC2-G-UNE2 implements the F2MC-8FX CPU core with 136 basic instructions, 1–3 byte instruction length, and support for 16-bit arithmetic, multiplication/division, and bit manipulation. Its memory subsystem includes 60 KB dual-operation Flash (allowing simultaneous program/erase and read in separate banks) and 2 KB SRAM.

Peripheral integration centers on real-time control and human interface: three UART/SIO channels (full-duplex double-buffered, NRZ format), one I²C master/slave interface with wake-up capability, eight-channel 8/12-bit ADC with software-selectable resolution, and a dedicated LCD controller with frame-sync interrupt, blinking, and inverted display functions - all coordinated via eight external interrupt channels with edge-selectable wake-up from Stop/Sleep/Watch/Time-base timer modes.

FAQ

What is the maximum operating frequency of the CY95F778EPMC2-G-UNE2?

The CY95F778EPMC2-G-UNE2 supports a maximum machine clock frequency of 16.25 MHz, achievable using the main PLL clock or external clock input. This frequency determines instruction execution speed (minimum 61.5 ns per instruction) and peripheral timing resolution, and is validated across the full -40°C to +85°C industrial temperature range with appropriate decoupling and layout practices.

Does this microcontroller support in-system programming (ISP)?

Yes, CY95F778EPMC2-G-UNE2 supports in-system programming via its on-chip debug interface using 1-wire serial control. It allows asynchronous serial writing of Flash memory without removing the device from the target board, enabling field firmware updates and production programming through standard UART or custom debug headers.

Can the LCD controller drive both static and multiplexed LCDs?

No - the integrated LCD controller supports only multiplexed (static drive is not implemented). It provides 4 or 8 COM outputs and up to 32 SEG outputs, configured for 32 SEG × 4 COM or 28 SEG × 8 COM layouts. The controller includes frame-synchronized interrupts, blinking, and inverted display functions tailored for common 7-segment and dot-matrix character displays.

Is the low-voltage detection (LVD) threshold configurable?

Yes, the LVD threshold is software-configurable via dedicated control registers. It offers multiple trip points (e.g., 4.0 V, 3.5 V, 3.0 V, 2.5 V) to match system-level brown-out requirements. When triggered, LVD asserts a reset signal to halt CPU execution and prevent unreliable Flash writes or register corruption during undervoltage conditions.
