ST10F276Z5Q3 개요

The STMicroelectronics ST10F276Z5Q3 is a high-performance 16-bit single-chip CMOS microcontroller from the ST10 family, delivering up to 32 MIPS at a 64 MHz CPU clock with a 50 ns instruction cycle time. It integrates a 16-bit CPU with a 4-stage pipeline, an enhanced boolean bit-manipulation unit, a single-cycle context switcher, and a Multiply/Accumulate (MAC) DSP extension featuring 16-bit multiplication and a 40-bit accumulator. The device is housed in a 144-pin PQFP package measuring 28 x 28 mm and integrates 832 Kbytes of on-chip Flash memory alongside 68 Kbytes of on-chip RAM.

A 16-bit microcontroller (MCU) is a programmable processor with a 16-bit data path, ALU, and register file. The ST10 family sits between classic 8-bit MCUs (8051, AVR, PIC16) and 32-bit Cortex-M cores in the broader taxonomy of embedded microcontrollers -> microprocessors -> digital logic ICs -> semiconductors. 16-bit MCUs are chosen when engineers need more arithmetic precision than an 8-bit core can deliver (16-bit DSP-style MAC operations, faster table lookups, larger linear address space) without paying the cost, power and code-size penalty of a 32-bit ARM core.

Key features include a 16 MByte linear address space, an integrated 12-channel A/D converter, a Capture/Compare unit, PWM timers, a CAN 2.0B interface, an ASC (asynchronous serial) port, and an SSC (synchronous serial) port. The ST10F276Z5Q3 also provides up to 111 general-purpose I/O lines, an on-chip CAN module, and support for boundary-scan/JTAG. The 144-pin PQFP package provides ample pin budget for parallel bus expansion and external memory interfacing while remaining compatible with surface-mount reflow.

Architecturally, the ST10F276Z5Q3 uses a Harvard-style bus with separate program and data paths, plus a 32-bit on-chip peripheral bus (XBUS) for connecting external peripherals and memory to the same internal address space. The MAC unit and enhanced boolean bit manipulation accelerate control-loop and DSP-style algorithms common in industrial drives and automotive ECUs, while the single-cycle context switch and fast interrupt response make the core well suited to deterministic real-time control.

Typical applications include industrial automation and motor control (variable-frequency drives, servo drives, PLCs), automotive body and powertrain ECUs, building automation controllers (HVAC, access control), medical instrumentation, and high-end consumer appliances. The combination of large on-chip Flash, generous RAM, and DSP-capable arithmetic supports sensor-fusion and closed-loop control without an external DSP.

When designing with this device, allocate sufficient PCB area around the 28 x 28 mm PQFP footprint for thermal dissipation and routing fan-out, place a 100 nF decoupling capacitor on each VDD pin, and provide a low-impedance ground return for the analog VDD/AGND pair that supplies the on-chip A/D converter. Designers should also verify the latest lifecycle status with ST before committing to long-life programs, as ST10 family derivatives have transitioned toward NRND status for several package variants.

일반적인 애플리케이션

ST10F276Z5Q3 적합 용도: 8 애플리케이션s: Industrial Variable-Frequency Motor Drives, Automotive Body and Powertrain ECUs, Industrial PLC and Process Controllers, Building Automation and HVAC Controllers, Medical Instrumentation and Patient Monitoring, Power Conversion and UPS Systems, Elevator and Escalator Control, Industrial Sensor Hubs and Fieldbus Nodes.

🏭

Industrial Variable-Frequency Motor Drives

The ST10F276Z5Q3's 64 MHz 16-bit ST10 core with hardware MAC unit and 50 ns instruction cycle is well-matched to closed-loop field-oriented control (FOC) of three-phase AC induction and permanent-magnet motors. The 832 Kbytes of Flash store motor-control firmware, FOC lookup tables and current-loop coefficients, while the 68 Kbytes of RAM hold ADC sample buffers and observer state. The on-chip CAN 2.0B controller links the drive to a higher-level PLC or servo controller. Placed on the control board between the gate driver and the current/voltage sensors, the ST10F276Z5Q3 executes a 10-20 kHz torque loop with deterministic interrupt latency thanks to its single-cycle context switching.

🚗

Automotive Body and Powertrain ECUs

The ST10F276Z5Q3 is widely deployed in automotive body and powertrain ECUs where deterministic 16-bit arithmetic, on-chip CAN and PWM timers are required. Its 832 Kbytes of Flash supports complex OBD-II diagnostic stacks and torque-management firmware, while the integrated CAN 2.0B and 12-channel A/D remove the need for an external ADC. In a typical engine ECU the ST10F276Z5Q3 runs the crank-shaft angle scheduler (using Capture/Compare), reads MAP/MAF/O2 sensors through the A/D, and broadcasts the resulting engine state onto the CAN bus. The 144-pin PQFP package is automotive-line compatible with wave and reflow soldering. Note that for new automotive programs ST recommends migrating to SPC56 / SPC58 Power Architecture parts.

🏭

Industrial PLC and Process Controllers

Programmable Logic Controllers (PLCs) and process-control blocks benefit from the ST10F276Z5Q3's 16 Mbyte linear address space, 68 Kbytes of RAM and dual serial interfaces (ASC + SSC). The MCU executes IEC 61131-3 logic and ladder-diagram scans at deterministic cycle times, while the 12-channel on-chip A/D samples 4-20 mA loop inputs and thermocouples for process variables. The 111 GPIO lines provide abundant discrete I/O for relay drivers and indicator LEDs without external I/O expanders. The 144-pin PQFP gives mechanical compatibility with legacy PLC form factors. Compared with an 8-bit 8051, the ST10F276Z5Q3 quadruples scan time headroom and adds DSP-grade MAC for PID tuning math.

🧩

Building Automation and HVAC Controllers

Building-automation controllers for HVAC, lighting and access control typically need a balance of on-chip Flash for application firmware, CAN for fieldbus networking, and PWM outputs for valve and damper actuation. The ST10F276Z5Q3's 832 Kbytes of Flash accommodates BACnet/Modbus stacks plus HVAC control loops, while the PWM timers drive proportional valves and 3-speed fan outputs. The 12-channel A/D reads room temperature, humidity and pressure sensors through standard 4-20 mA or 0-10 V transducer interfaces. The single-cycle context switching ensures low interrupt latency for safety-critical fire/smoke damper commands. The 144-pin PQFP package provides ample pin budget for a backplane connector and field-wiring terminal block.

💊

Medical Instrumentation and Patient Monitoring

Medical instruments such as infusion pumps, ventilators and patient monitors require a deterministic 16-bit MCU with reliable Flash for code integrity. The ST10F276Z5Q3's single-cycle context switching supports the precise dosing intervals of infusion pumps and the real-time alarm handling required by IEC 60601 patient monitors. The on-chip 12-channel A/D captures ECG, SpO2 and respiration signals through external instrumentation amplifiers; the MAC unit accelerates FIR filtering of the bioelectric waveforms. The 832 Kbytes of Flash supports the safety-critical firmware with built-in self-test routines. Designers should add a watchdog supervisor and follow ST's safety manual for medical-device integration.

⚡

Power Conversion and UPS Systems

Uninterruptible Power Supplies (UPS), solar inverters and three-phase PFC stages require high-resolution PWM and deterministic ADC sampling of current/voltage waveforms. The ST10F276Z5Q3's Capture/Compare unit generates the high-resolution PWM edges needed for digital-control PFC, while the 12-channel A/D simultaneously samples the inductor current and the rectified mains voltage. The MAC unit executes the digital-control math (current-loop PI, power-loop PID) within a 20-50 kHz control cycle. The CAN 2.0B interface reports telemetry to a system supervisor. The 144-pin PQFP gives designers ample pins for IGBT gate-driver enable signals, relay control and the user-interface LCD.

✈️

Elevator and Escalator Control

Elevator controllers and escalator drives demand a 16-bit deterministic MCU with CAN bus connectivity and abundant PWM channels for contactor control. The ST10F276Z5Q3's 144-pin PQFP provides enough GPIO for door-zone sensors, floor-level indicators, safety-chain monitoring and brake contactor drives. The on-chip CAN 2.0B controller interfaces with the elevator group supervisor and remote monitoring system. The 832 Kbytes of Flash stores the cabin-position lookup tables, safety logic and diagnostic logs. The hardware MAC unit accelerates the closed-loop motor-control math that keeps cabin position accurate to the millimeter. Note: for new elevator designs EN 81-20/50 certification may require migration to a newer safety-certified MCU family.

🌐

Industrial Sensor Hubs and Fieldbus Nodes

Industrial fieldbus nodes (Profibus, CANopen, DeviceNet) need an MCU with on-chip CAN, plenty of Flash for protocol stacks and PWM/timer resources for sensor excitation. The ST10F276Z5Q3's integrated CAN 2.0B and 12-channel A/D let it act as a smart sensor hub, digitizing 4-20 mA inputs and publishing them on the CAN bus. The 68 Kbytes of RAM buffer incoming CAN frames while the 832 Kbytes of Flash store the DeviceNet CIP object library. The Capture/Compare unit generates the PWM excitation for two-wire and three-wire vibration sensors. The 144-pin PQFP and -40 to +125 C temperature range suit IP67 field enclosures.

What is the CPU clock frequency and instruction cycle time of ST10F276Z5Q3?
The ST10F276Z5Q3 runs at a maximum 64 MHz CPU clock, which corresponds to a 50 ns instruction cycle time at 40 MHz per the ST10F276 datasheet data brief. At this speed the core delivers up to 32 MIPS (32 million instructions per second), making it suitable for high-performance real-time control loops and DSP-style MAC operations.
How much Flash and RAM does ST10F276Z5Q3 have?
The ST10F276Z5Q3 integrates 832 Kbytes of on-chip Flash program memory and 68 Kbytes of on-chip RAM. This large single-chip memory footprint enables complex state machines, lookup tables and DSP coefficient storage without external memory, simplifying PCB design and bill of materials.
Does ST10F276Z5Q3 have a DSP or MAC unit?
Yes. The ST10F276Z5Q3 includes a hardware Multiply/Accumulate (MAC) unit providing 16-bit multiplication and a 40-bit accumulator, plus enhanced boolean bit-manipulation instructions. The MAC unit accelerates closed-loop control algorithms, FIR/IIR filters and other DSP-style math that 16-bit microcontrollers without a MAC would handle far less efficiently.
What package does ST10F276Z5Q3 use?
The ST10F276Z5Q3 is housed in a 144-pin Plastic Quad Flat Package (PQFP) measuring 28 x 28 mm. The 144-pin PQFP footprint provides ample routing area for the 16-bit external bus and the up to 111 GPIO lines while remaining compatible with standard surface-mount reflow profiles.
Where can I download the ST10F276Z5Q3 datasheet PDF?
The ST10F276Z5Q3 datasheet (covering the ST10F276 family) is published by STMicroelectronics and is available from ST's product documentation portal, as well as from distributor datasheet mirrors such as alldatasheet and datasheet4u. Search 'ST10F276' on www.st.com to retrieve the latest revision and errata.
What is the pinout of ST10F276Z5Q3?
The 144-pin PQFP pinout is documented in the ST10F276 family datasheet. Because the package is 28 x 28 mm with 144 leads, the pin assignment covers supply pins (VDD/VSS pairs), PORTC/PORTE/PORTF parallel-bus pins, ADC analog inputs, CAN, ASC and SSC pins, plus JTAG/boundary-scan pins. Refer to the datasheet pin map before PCB layout.
Is ST10F276Z5Q3 still in production?
According to distributor data, the ST10F276Z5Q3 lifecycle stage is ACTIVE per digchip listings, but ST has flagged certain ST10 family derivatives as NRND (Not Recommended for New Design) per the ST community forum. Confirm the latest status on ST's product page before committing to long-life industrial or automotive programs.
What is the price of ST10F276Z5Q3 in 2026?
As of 2026-10-10, distributor pricing for the ST10F276Z5Q3 ranges roughly from USD 18-33 per unit depending on quantity break, with tier-1 distributors (DigiKey, Mouser) carrying stock and tier-2/3 distributors (Wolfchip, Veswin, Expertonic) offering broader inventory. Real-time price and stock should be checked on Octopart, which compares 20 distributors.
Where can I buy ST10F276Z5Q3 online?
The ST10F276Z5Q3 is in stock at authorized distributors including DigiKey (digi-key p/n 1220113) and Mouser, plus independent distributors such as Wolfchip (30900 pcs reported on 2026-05-20), Veswin, Expertonic, and AiPCBA.

ST10F276Z5Q3 vs ST10F276Z5T3 - what is the difference?
The ST10F276Z5Q3 and ST10F276Z5T3 share the same ST10F276 silicon, Flash/RAM (832KB/68KB), MAC unit and 144-pin count, but differ in package temperature grade and exposed-pad style. The Q3 suffix typically denotes a different PQFP/JEDEC package variant than the T3; both are 144-pin but are not strictly drop-in pin-for-pin compatible, so verify the mechanical drawing before substituting.
What is the best drop-in replacement for ST10F276Z5Q3?
The closest drop-in same-package alternative is the ST10F276Z5T3, which shares the same ST10F276 die, Flash/RAM and 144-pin count. Both parts originate from the ST10F276 family datasheet. For legacy boards requiring exact pinout, the T3 variant is the engineering-recommended substitute; for new designs ST recommends migrating to STM32F4-class Cortex-M parts.
When should I choose ST10F276Z5Q3 over an STM32 Cortex-M part?
Choose the ST10F276Z5Q3 when you have a legacy 16-bit ST10 codebase to maintain or when you need deterministic 16-bit MAC performance with a flat 16 Mbyte linear address space. Choose an STM32 Cortex-M part for new designs where you benefit from ARM ecosystem support, lower power, and a much larger 32-bit software ecosystem. Both are ST products, so migration is supported.
Is ST10F276Z5Q3 RoHS compliant?
Yes, the ST10F276Z5Q3 is listed as RoHS compliant by STMicroelectronics product listings and by distributor data. However, a GlobalSpec datasheet entry indicates the family is flagged 'Not Compliant' for Halogen-Free, so if your design requires halogen-free components, qualify an alternative such as ST10F276Z5T3-HF or move to STM32.
What communication peripherals does ST10F276Z5Q3 provide?
The ST10F276Z5Q3 integrates a CAN 2.0B controller, an asynchronous serial channel (ASC), a synchronous serial channel (SSC), a 12-channel on-chip A/D converter, Capture/Compare timers, PWM timers, and JTAG/boundary-scan support. This peripheral set covers the standard industrial and automotive fieldbus needs for CAN-based motor control and sensor interfacing.

선택 가이드

Choose the ST10F276Z5Q3 when designing a new industrial or automotive embedded controller that requires 832 Kbytes of on-chip Flash, 64 MHz CPU clock with hardware MAC DSP, and an extensive on-chip peripheral set (CAN 2.0B, ASC, SSC, 12-channel A/D, Capture/Compare). It is the right choice for motor-control, PLC, HVAC and automotive-ECU applications where a deterministic 16-bit core is needed. Choose the ST10F276Z5T3 if you need an exact same-die alternate but can accept NRND status for legacy support. Choose the ST10F273Z5 if your firmware fits in 512 Kbytes and you want to qualify a proven sibling. Cross-brand alternatives (Infineon XC886, NXP S12X) require firmware rewrite and PCB re-validation - they are only suitable when an ST source is unavailable.

설계 노트

The ST10F276Z5Q3 has multiple VDD/VSS pin pairs distributed around the 144-pin PQFP. Place a 100 nF decoupling capacitor adjacent to each VDD/VSS pair, and add a bulk 10 uF tantalum or ceramic capacitor near the package corner closest to the analog VDD/AVDD/AGND/VAREF pins. The analog supply V_AREF should be driven from a low-noise reference (REF102 or equivalent) to obtain full A/D converter accuracy, and V_AGND should return to the ground plane at a single point away from digital return currents.

The 144-pin PQFP at 28 x 28 mm has 0.65 mm pitch leads and an exposed lead-frame footprint. Provide at least 8 mils of trace-and-space on outer layers to fan out from the leads, and reserve a continuous ground pour under the package to reduce digital switching noise coupling into the analog section. For high-speed CAN, place the CAN transceiver within 25 mm of the ST10F276Z5Q3's CAN_TX/CAN_RX pins to keep the differential pair short and 100 ohm-terminated.

Do not exceed 64 MHz on XTAL1/XTAL2 - the on-chip PLL multiplies the external crystal frequency and is rated only for the 4-8 MHz fundamental-mode range. A common design pitfall is to treat ST10F276Z5Q3 and ST10F276Z5T3 as identical pinout parts; verify the exact mechanical drawing because the Q3 and T3 package suffixes differ in lead finish / thermal pad treatment. Always hold the MCU in reset (drive RSTIN low) until the 5 V supply rail has stabilized, and verify boot-mode strap pins (EA, BRKOUT) at power-up.

Estimated: at 64 MHz CPU clock, VDD = 5 V and 80 % CPU duty cycle, the ST10F276Z5Q3 dissipates approximately 300-450 mW. The 144-pin PQFP thermal resistance is approximately 35-40 C/W (theta_JA), so junction temperature rise is roughly 15-20 C above ambient at 25 C. For industrial-grade designs with ambient up to 85 C the junction temperature stays well below the 125 C maximum. Add a small copper heatsink pattern on the top layer if the design runs near maximum CPU load continuously.
