Jade Microsystems industrial process control engineering

Jade Microsystems Limited developed electronic hardware platforms for industrial automation and process control under SIC category 26512.

Operating from Kenton in the United Kingdom, the company produced the JMS family of development boards, AVR-based microcontroller processor units and debugging accessories.

The engineering architecture is built around Atmel ATmega128 8-bit RISC microcontrollers. Standardized 8-way pin headers, onboard linear voltage regulators and integrated JTAG ICE debugging ports enabled fast prototyping and integration into factory production lines.

JMS2206 processor and development platform architecture

The JMS2206 evaluation board provides a complete hardware foundation for industrial sensor acquisition and actuator sequencing.

Driven by an Atmel ATmega128 microcontroller running from an onboard 4 MHz quartz crystal, the module integrates a 5-volt linear regulator with a DC power status indicator LED.

A 10-way IDC connector interfaces directly with external JTAG emulators and programmers for rapid firmware flashing and register analysis.

All digital and analog I/O lines are broken out into standardized 8-way pin connectors, allowing direct ribbon cable connections to field equipment without soldering.

Microcontroller core architecture: memory, clocks and interrupts

The ATmega128 microcontroller features an advanced Harvard RISC architecture executing instructions within single clock cycles. It contains 128 KB of in-system programmable flash memory, 4 KB of byte-addressable EEPROM for calibration constants and 4 KB of internal SRAM for operational variables.

Up to eight external hardware interrupt lines provide real-time responses to critical industrial limit switches and safety sensors. The 4 MHz crystal oscillator establishes stable system timing for internal timers, synchronous communications and pulse-width modulation generators.

Communication interfaces: dual UART ports, SPI bus and JTAG ICE

The JMS2206 architecture includes dual independent hardware UART serial ports for simultaneous telemetry exchange with operator panels and supervisory PLC networks. A high-speed synchronous serial peripheral interface (SPI) supports fast communication with peripheral ICs and input expansion modules.

The onboard JTAG ICE header facilitates non-intrusive in-circuit debugging, memory programming and hardware breakpoint execution. Technicians can inspect internal registers and monitor execution routines in active industrial control panels without interrupting electrical wiring.

Analog acquisition, 10-bit ADC and pulse-width modulation channels

The hardware incorporates an 8-channel 10-bit analog-to-digital converter with selectable VREF connection points. This enables precise scaling of industrial 0-10V and 4-20mA sensor signals monitoring temperature, fluid pressure and mechanical strain in automation machinery.

An on-chip analog comparator delivers hardware-level voltage threshold monitoring with near-zero latency for protective interlocking. Dual hardware PWM outputs generate accurate control signals for heating elements, positioning servomotors and proportional valve actuators.
