SC9S08LL36J1CLH557 概述
An 8-bit microcontroller is a single-chip processor that manipulates data in 8-bit words, combining CPU, memory, and peripherals in one package. Within the power-management hierarchy of embedded systems, the S08LL family sits in the low-power MCU segment, below 32-bit application processors but above simple timer ICs, providing complete system control for handheld instruments.
Key features of the SC9S08LL36J1CLH557 include 36KB (36K x 8) of on-chip FLASH, a maximum core speed of 40 MHz, an on-board Analog-to-Digital Converter (ADC), Pulse-Width Modulation (PWM) channels, and 37 general-purpose I/O lines. The device supports a minimum supply voltage of 1.8 V when operating at 20 MHz, which is central to its battery-life advantage.
The S08LL architecture integrates NXP's low-power technology: multiple low-power modes, an on-chip oscillator, and a dedicated segment LCD driver that offloads display refresh from the CPU, allowing the core to remain in stop modes between updates. This extends battery life in always-on display applications.
Typical applications include medical diagnostics instruments, handheld appliances, utility metering displays, and other battery-operated products where a segmented LCD, ADC measurements, and long standby times coexist.
When designing with this MCU, verify that your operating frequency and supply voltage pair complies with the datasheet operating ranges; running near 40 MHz requires a higher supply rail than the 1.8 V minimum used at 20 MHz.

典型应用
SC9S08LL36J1CLH557 适用于 6 应用s: Medical Diagnostics Handheld Instruments, Utility Metering Displays, Handheld Consumer Appliances, Industrial Panel Indicators, Portable Environmental Monitoring, Test and Measurement Hand Tools.
Medical Diagnostics Handheld Instruments
NXP positions the S08LL family explicitly for battery-powered medical diagnostics, and the SC9S08LL36J1CLH557 fits that role directly. Its integrated segment LCD controller drives the numeric and status displays typical of glucose meters and portable analyzers without CPU overhead, while the on-chip ADC digitizes sensor inputs such as electrochemical test strips. The 1.8 V minimum supply at 20 MHz allows operation from two alkaline cells with regulation headroom, and 36KB FLASH accommodates measurement algorithms, calibration tables, and user-interface code. During idle periods between measurements, the S08 core can rest in low-power stop modes while the LCD remains refreshed, directly extending battery service life in an always-on instrument.
推荐
Utility Metering Displays
Electricity, water, and gas meters require decades-long battery or energy-harvested operation with a readable segmented display. The SC9S08LL36J1CLH557 addresses this with its dedicated LCD driver, low standby current characteristic of the S08LL family, and voltage-frequency scaling that lets firmware drop from 40 MHz to 20 MHz and below when running from a 1.8 V-minimum rail. The 37 GPIO lines handle pulse inputs, tamper switches, and communication flags, while PWM channels drive indicator LEDs or buzzer output. With 36KB FLASH, metering firmware including register tables and multi-tariff logic fits without external memory, keeping the bill of materials to a single MCU, the LCD, and the metrology front end.
推荐
Handheld Consumer Appliances
Remote controls, kitchen timers, personal scales, and thermostats all combine segmented LCDs, a few buttons, and strict cost ceilings. The SC9S08LL36J1CLH557 consolidates the MCU, LCD driver, and ADC (for scale load cells or thermostat sensors) into one 64-LQFP CMOS device, eliminating a separate LCD controller chip. The 40 MHz S08 core provides ample headroom for debouncing, display multiplexing, and simple control loops, and 37 GPIO covers button matrices and annunciator segments. Running the core at 20 MHz from a 1.8 V-class rail during standby extends coin-cell life, a decisive consumer-battery requirement for handheld appliances sold at high volume.
推荐
Industrial Panel Indicators
Low-cost industrial panel meters and status indicators benefit from the SC9S08LL36J1CLH557's combination of a segment LCD driver, ADC, and 37 GPIO in a single 64-LQFP package. The ADC reads 4-20 mA-derived sensor voltages or potentiometer setpoints, the PWM channels generate alarm tones or analog control outputs, and the LCD shows measured values and fault codes. The S08 core's 40 MHz maximum clock leaves performance margin for communication framing over a UART-to-RS-485 link implemented in GPIO or an external transceiver. Because the die is the same as the widely stocked MC9S08LL36CLH, industrial buyers can dual-source the footprint across NXP catalog and legacy channels.
推荐
Portable Environmental Monitoring
Battery-powered environmental sensors - thermometers, hygrometers, air-quality badges - need periodic ADC sampling of analog sensor elements and a persistent display of readings. The SC9S08LL36J1CLH557's on-chip ADC digitizes resistive or voltage-output sensors, the segment LCD controller keeps values visible with negligible energy, and the S08 core wakes on a timer or button press to run a conversion and update segments. Operation at a 1.8 V minimum supply at 20 MHz suits single-cell lithium or two-cell alkaline designs, while 36KB FLASH stores calibration curves, min/max logging, and alarm logic. This integration minimizes component count on small portable PCBs.
推荐
Test and Measurement Hand Tools
Entry-level multimeters, capacitance meters, and component testers use a segmented LCD, a rotary switch matrix, and modest compute - an ideal match for the SC9S08LL36J1CLH557. The built-in ADC performs the primary measurement at low power, the 37 GPIO lines scan the function switch ring and button pad, and PWM can drive continuity beepers or backlight control. The 40 MHz S08 core handles range auto-selection and display formatting, and 36KB FLASH holds firmware for multiple measurement modes without banking external memory. Distributor availability through LCSC and JLCPCB (part C5746271) makes prototyping and low-volume instrument builds straightforward.

设计说明
Respect the S08LL voltage-versus-frequency operating envelope: the device supports a 1.8 V minimum supply only at reduced speed (documented at 20 MHz), while the full 40 MHz core clock requires a higher rail. For battery products, implement a firmware-driven scaling strategy - run fast at a higher VDD during active measurement, then drop frequency and voltage for display-refresh idle periods. Verify the exact envelope in the S08LL datasheet operating-range graph before finalizing the regulator output voltage, and budget regulator quiescent current into the battery-life calculation.
For the 64-LQFP footprint, place a 100 nF ceramic decoupling capacitor at each VDD pin pair, as close to the pins as possible, plus a bulk 4.7-10 uF capacitor near the supply entry. Keep the analog supply feeding the ADC separated from noisy digital returns with a star ground or a segmented ground plane, since the on-chip ADC accuracy directly affects measurement resolution in metering and diagnostics applications. Route LCD segment lines away from switching regulator nodes to prevent visible ghosting on the glass.
This is a legacy Freescale-era part: use the classic CodeWarrior S08 toolchain and a BDM debug probe, not MCUXpresso, which does not support S08 devices. Second, ordering codes matter when sourcing - SC-prefixed parts route through legacy/authorized-aftermarket channels (Rochester Electronics) while MC-prefixed parts come from the NXP catalog; confirm the exact MPN against your approved vendor list before release. Finally, verify that the '557' packing/lead-free suffix on your PO matches your assembly process requirements to avoid receiving reflow-incompatible stock.
合规信息
The '557' suffix in NXP ordering codes conventionally denotes a specific packing/finish option, but the sourced web data does not explicitly state RoHS/REACH/lead-free status. Verify compliance certificates from NXP or Rochester Electronics before ordering for regulated markets.
