Product details

Overview

CY7C63001C-SXC from Cypress Semiconductor is an 8-bit RISC OTP microcontroller with integrated low-speed USB 1.1 interface engine (1.5 Mbps), 4 KB EPROM, 128-byte RAM, and 12 GPIOs-12 of which are Schmitt-trigger inputs with programmable pull-ups and sink-current control. It supports one USB device address and two endpoints (control + data), and operates from 4.0–5.25 V at 0–70 °C in 20-pin SOIC package. Used in cost-sensitive human-interface devices like optical mice.

For engineers reviewing the CY7C63001C-SXC datasheet, CY7C63001C-SXC pinout, CY7C63001C-SXC application, or CY7C63001C-SXC equivalent, key selection criteria include USB 1.1 low-speed compliance, OTP programmability, integrated transceiver, 12-GPIO allocation across Port 0 (low-current) and Port 1 (high-current), and suspend/wake-up timing via CEXT pin.

Technical Context

The CY7C63001C implements a Harvard-architecture RISC core running at 12 MHz derived from a 6-MHz ceramic resonator, with 35 USB-optimized instructions. Its USB Serial Interface Engine (SIE) handles token, data, and handshake phases without CPU intervention, supporting only low-speed (1.5 Mbps) operation per USB 1.1.

Memory includes 4 KB of OTP EPROM (with 16-byte interrupt vector table) and 128-byte RAM-of which 16 bytes are reserved as dual 8-byte FIFOs for Endpoint 0 and Endpoint 1. The device features three reset sources (POR, WDR, USB Bus Reset), each flagged in SCR register (0xFF), and supports instant wake-up from suspend mode via GPIO edge interrupts or CEXT RC timeout.

Key Specifications

Parameter	Value and Actual Design Meaning
USB Speed	Low-speed only: 1.5 Mbps, compliant with USB 1.1 specification - limits use to HID-class peripherals, no full-speed support.
Microcontroller Core	8-bit Harvard RISC, 12-MHz internal clock from 6-MHz external ceramic resonator - eliminates need for crystal oscillator circuitry.
Memory	4 KB OTP EPROM + 128-byte RAM (16 bytes reserved for dual 8-byte USB endpoint FIFOs) - fixed program storage, no reprogrammability after programming.
I/O Pins	12 total GPIOs: P0.0–P0.7 (8 low-current, Schmitt-trigger) + P1.0–P1.3 (4 high-current, LED-drive capable) - enables direct LED driving without external drivers.
Power Supply	4.0 V to 5.25 V DC - compatible with standard USB bus power (5 V ±5%) and tolerates brown-out conditions down to 4.0 V.
Operating Temperature	0 °C to +70 °C - suitable for commercial-grade peripheral applications, not extended industrial or automotive environments.
Suspend/Wake-up	Hardware-supported suspend mode with wake-up on USB activity, GPIO edge interrupt, or CEXT RC timeout - achieves sub-100 µA average current in periodic polling.

Pinout & Package

Package: 20-pin SOIC (Small Outline Integrated Circuit), surface-mount, 0.300-inch body width, standard JEDEC MS-013AC footprint.

Pin/Terminal	Circuit Role	Design Meaning
P0.0–P0.3	Port 0 I/O (low-current)	Schmitt-trigger inputs with programmable pull-ups; sink current configurable in 16 levels - ideal for switch/encoder inputs in mouse wheel or button logic.
P0.4–P0.7	Port 0 I/O (low-current)	Same electrical characteristics as P0.0–P0.3; pins 20, 19, 18, 17 in SOIC - used for auxiliary sensing or status signaling.
P1.0–P1.3	Port 1 I/O (high-current)	LED-drive capable (up to 20 mA sink); pins 5, 16, 6, 15 in SOIC - directly drives status LEDs or photo-transistor bias in optical mouse modules.
D+, D–	USB differential data pair	Bidirectional low-speed USB lines; require external 1.5-kΩ pull-up on D– to VCC to signal low-speed device - no external transceiver needed.
XTALIN/XTALOUT	Ceramic resonator interface	Accepts 6-MHz ceramic resonator (not crystal); internal doubler generates 12-MHz core clock - reduces BOM count and EMI vs. crystal-based designs.
CEXT	RC wake-up timer input/output	Open-drain output with Schmitt trigger input; connects to external R-C network to generate precise wake-up intervals during suspend - enables battery-efficient polling.
VCC / VSS	Power supply / ground	VCC: 4.0–5.25 V; VSS: system ground reference - decoupling capacitor required near pin 12 (VCC) for stable USB signaling.
VPP	EPROM programming voltage	12.5 V input during OTP programming; must be tied to GND during normal operation - prevents accidental reprogramming in field use.

Key Features

Feature	Design Value
Integrated USB SIE + transceiver	Eliminates external PHY and protocol logic; reduces PCB area and component count for HID-class peripherals.
Instant-On Now™ suspend/wake-up	Full USB functionality restored within 256 µs after wake event - meets USB resume timing requirements without firmware delay.
Programmable I/O sink current (16 levels)	Enables precise LED brightness control and noise-immune switch debouncing without external resistors or drivers.
Maskable GPIO interrupts on all pins	Edge-triggered, polarity-programmable interrupts allow responsive real-time input handling (e.g., mouse movement detection).
On-chip 8-bit free-running timer + WDT	Timer provides 1.024-ms tick for CEXT wake-up and firmware scheduling; WDT prevents lock-up with 8.192-ms timeout.

Gamepad Controller

USB Keypad

Use Scenario: Multi-button + D-pad + analog stick interface with vendor-defined HID reports.

IC Role / Device Role / Timing Role: Input aggregator and USB endpoint manager handling up to 12 discrete inputs and 2 analog thresholds.

Use Value: Dual-port architecture isolates button matrix (P0) from LED feedback (P1); suspend mode reduces average current to <50 µA during inactivity.

Equivalent & Alternatives

The following parts are listed as comparable options for similar low-speed USB HID controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
FTDI FT230X	USB-to-serial bridge IC (no MCU core); requires external microcontroller for HID logic.	Needs separate MCU + firmware to implement HID report generation - increases BOM, PCB area, and development time.	Choose only if existing design already uses UART-based MCU and requires minimal USB interface layer.
Microchip PIC18F14K50	Flash-based 8-bit MCU with USB 2.0 full-speed peripheral module; requires external USB transceiver and crystal.	Supports full-speed (12 Mbps) and custom class descriptors; higher code density and debug flexibility than OTP.	Select when future firmware updates, USB descriptor customization, or higher bandwidth are required.

Compared with FT230X and PIC18F14K50, the CY7C63001C-SXC delivers lowest system-level cost and smallest footprint for fixed-function low-speed HID devices, trading flash reprogrammability and full-speed capability for integrated SIE, OTP security, and zero-external-component USB connectivity.

FAQ

Is the CY7C63001C-SXC compatible with USB 2.0 hosts?

Yes, it is backward compatible with all USB 2.0 and later hosts because it implements the USB 1.1 low-speed (1.5 Mbps) specification. Host controllers automatically negotiate low-speed mode when the 1.5-kΩ pull-up resistor is detected on D–, ensuring plug-and-play operation without driver changes.

Can the EPROM be reprogrammed after initial programming?

No. The CY7C63001C-SXC uses One-Time Programmable EPROM. Once programmed, the firmware and configuration data cannot be altered. This ensures firmware integrity and prevents unauthorized modification in production HID devices.

What is the role of the CEXT pin in power management?

The CEXT pin connects to an external resistor-capacitor network to generate a precise wake-up interval during suspend mode. When the RC time constant expires, it triggers a hardware interrupt that exits suspend and resumes full operation - enabling ultra-low-power periodic polling of sensors or switches.

Does this device require an external USB transceiver?

No. The CY7C63001C-SXC integrates a full low-speed USB transceiver, including differential drivers, receivers, and line-state detectors. Only two external components are required: a 6-MHz ceramic resonator and a 1.5-kΩ pull-up resistor on D– to VCC.
