Product details
Overview
CY95F778EPMC1-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 cost-sensitive, display-driven applications such as appliance UIs and industrial HMI panels.
For engineers reviewing the CY95F778EPMC1-G-UNE2 datasheet, CY95F778EPMC1-G-UNE2 pinout, CY95F778EPMC1-G-UNE2 application, or CY95F778EPMC1-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 configurable A/D converter across 8 channels - all critical for reliable, low-power, real-time control in resource-constrained systems.
Technical Context
The CY95F778EPMC1-G-UNE2 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 operations. Its memory subsystem includes dual-operation Flash (60 KB) allowing simultaneous program/erase in one bank while executing code from another, plus 2 KB RAM with dedicated register banks for fast context switching.
Peripherals are tightly integrated for display-centric control: an LCD controller with software-selectable internal divider resistors (10 kΩ or 100 kΩ), frame-sync interrupt, blinking/inverted display functions; three UART/SIO channels with full-duplex double buffering and NRZ format; and a 1-channel I²C interface with wake-up capability. Clock supervision includes both main and subclock oscillation monitoring via dedicated hardware counter.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit display-oriented microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RL78/L12 (R5F10PLGSP#V0) | 16-bit RL78 core, 64 KB Flash, 6 KB RAM, 44-pin HWQFN; no native LCD controller - requires external bias or driver IC | Higher performance but lacks integrated LCD drive; better suited for sensor fusion + connectivity vs. pure display control | Select when needing CAN/LIN interface or higher computational throughput; avoid when minimizing BOM count for LCD systems |
| STM8L152C6T6 | 8-bit STM8 core, 32 KB Flash, 2 KB RAM, 38 I/O; integrated LCD controller supports only up to 8×28 segments and fixed 20 kΩ bias | Lower Flash capacity and fewer I/O; LCD configuration less flexible than CY95F778E's software-selectable resistors and COM/SEG mapping | Choose for ultra-low-power (<300 nA Stop mode) designs where display complexity is minimal and cost is primary constraint |
Compared with RL78/L12 and STM8L152C6T6, the CY95F778EPMC1-G-UNE2 uniquely balances display integration (28×8 LCD + programmable bias), field-upgradable Flash, and robust low-voltage operation - making it optimal for cost-sensitive, maintenance-aware appliance and industrial panel designs requiring long-term component stability.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for CY95F778EPMC1-G-UNE2?
The CY95F778EPMC1-G-UNE2 supports a maximum machine clock frequency of 16.25 MHz, achieved via main PLL or external clock input. At this frequency, the minimum instruction execution time is 61.5 ns. The F2MC-8FX core executes most instructions in 1–3 machine cycles, with multiplication and division requiring fixed-cycle counts documented in the instruction set manual (Rev. *E, Section 13).
Does CY95F778EPMC1-G-UNE2 support in-system programming (ISP) and how is it implemented?
Yes, the CY95F778EPMC1-G-UNE2 supports in-system programming via its on-chip debug interface using 1-wire serial control. Programming is performed asynchronously through dedicated debug pins (DBG and VPP), allowing flash writes and erases without removing the device from the target board. Serial writing is enabled in boot mode, and security bits can lock the Flash against unauthorized access.
How does the LCD controller handle bias voltage generation and what external components are required?
The LCD controller integrates an internal divider resistor network with software-selectable values of 10 kΩ or 100 kΩ, eliminating the need for external bias resistors in most configurations. Bias voltage is generated from VDD and applied across COM/SEG lines; the controller supports static and multiplexed (4- or 8-COM) drive schemes. Only external capacitors (typically 100 nF) are required for charge pump stabilization.
What are the power supply requirements and low-voltage protection features of CY95F778EPMC1-G-UNE2?
The CY95F778EPMC1-G-UNE2 operates from 2.7 V to 5.5 V DC on VDD, with separate VSS reference. It includes a built-in low-voltage detection (LVD) circuit that generates a reset when VDD falls below a user-programmable threshold (selectable from 2.7 V to 4.5 V in 0.1 V steps). Power-on reset (POR) is also integrated and activates at ~2.0 V during startup.
