LPC55S28JBD64K Обзор

The NXP LPC55S28JBD64K is a 32-bit microcontroller based on the Arm Cortex-M33 core running at up to 150 MHz, with 512 KB on-chip flash memory, 104 KB SRAM, and a 3.3 V supply, housed in a 64-pin HTQFP (10x10 mm) exposed-pad package.

A microcontroller (MCU) is a complete computing system on a single chip, integrating a processor core, non-volatile program memory, SRAM, and peripherals such as UART, SPI, I2C, ADC, and timers. The LPC552x/S2x family belongs to NXP's LPC5500 series within the broader EdgeVerse edge computing platform, targeting general embedded and industrial IoT applications.

Key features of the LPC55S28 include the Armv8-M mainline architecture with TrustZone hardware security, a PRINCIPE-based secure boot flow in the 'S' variant, and a cost-effective 40-nm NVM process. The Cortex-M33 core with DSP instructions delivers high performance efficiency for signal-processing workloads, while the dual-bank flash architecture supports in-field firmware updates. Peripherals include Flexcomm serial interfaces, dual 12-bit ADCs, USB full-speed device, and multiple timer/PWM blocks.

Technically, the LPC55S2x leverages pin-, software- and peripheral-compatibility across the LPC552x/S2x family, letting designers scale flash density or security features without PCB redesign. According to NXP, the family provides a balance of security, performance efficiency, and system integration for general embedded markets.

Typical applications include industrial IoT nodes, secure connected devices, motor control and digital power, consumer appliances, and medical monitoring equipment, where 150 MHz real-time performance and TrustZone-based security are required.

When designing with this part, plan the power architecture around a 1.8-3.6 V supply range and use the exposed thermal pad for ground connection and improved signal integrity. Ensure SWD and ISP programming pads are accessible for production flash and debug.

Типичное применение

LPC55S28JBD64K подходит для 6 применениеs: Industrial IoT Edge Nodes, Motor Control and Digital Power, Secure Connected Devices, Consumer Appliances, Medical Monitoring Equipment, Building Automation and Access Control.

🧩

Industrial IoT Edge Nodes

The LPC55S28JBD64K fits industrial IoT nodes that need secure connectivity and real-time local processing. Its 150 MHz Cortex-M33 core with DSP instructions handles protocol stacks, sensor fusion, and local analytics, while TrustZone and secure boot protect device identity keys and firmware integrity against physical tampering. The 512 KB flash accommodates an RTOS, a TCP/MQTT stack, and OTA update banks, and the 104 KB SRAM buffers telemetry without external memory. Flexcomm serial interfaces connect to Ethernet MACs, RS-485 transceivers, or Wi-Fi/BLE modules, and the dual 12-bit ADCs digitize analog sensors directly. Deployed between sensor front-ends and cloud gateways, it adds no switching noise and keeps deterministic response under load.

⚡

Motor Control and Digital Power

For BLDC/PMSM drives and digital power supplies, the LPC55S28JBD64K provides the combination of a 150 MHz core, hardware PWM timers, and dual 12-bit ADCs needed for field-oriented control loops at tens of kilohertz. DSP instructions accelerate Clarke/Park transforms and PI current loops, while deterministic Cortex-M33 interrupt latency keeps current sampling phase-aligned. The 512 KB flash holds sensorless observers and parameter self-tuning routines with room for OTA updates. Complementary gate drivers and supervisors from the XAIPART catalog complete the power stage; the MCU reads bus voltage and phase currents through its ADCs and modulates the inverter with high resolution, all from a single 3.3 V rail.

🎥

Secure Connected Devices

Products that must protect credentials - payment terminals, smart locks, authenticated accessories - benefit from the LPC55S28's TrustZone isolation and NXP secure boot. The Cortex-M33 mainline architecture partitions a secure world holding keys and cryptographic routines from a non-secure application world, so even a compromised application cannot extract root secrets. Secure boot verifies signed firmware on every reset, and the dual-bank 512 KB flash enables fail-safe encrypted OTA updates with rollback. USB full-speed device support covers physical provisioning and user connectivity. Compared with bolting on a separate secure element, this single-chip approach reduces BOM cost while keeping the root of trust on-die.

🔧

Consumer Appliances

In appliances such as cooktops, air conditioners, and power tools, the LPC55S28JBD64K serves as the main control MCU driving user interfaces, sensor monitoring, and motor control. The 150 MHz core leaves headroom for capacitive-touch processing and display updates while running the main state machine, and Flexcomm UART/SPI/I2C interfaces connect displays, EEPROMs, and communication modules. The dual 12-bit ADCs monitor temperatures, currents, and user inputs, and timer/PWM blocks drive fans and compressors. With 512 KB flash, one firmware image can serve multiple appliance SKUs with feature flags, reducing firmware variant count. Its industrial temperature behavior and 3.3 V operation simplify power design in mains-powered products.

💊

Medical Monitoring Equipment

Portable and bedside medical monitors use the LPC55S28JBD64K to acquire physiological signals, filter them, and relay data to displays or gateways. The dual 12-bit ADCs sample patient sensors, while DSP instructions implement real-time digital filtering of ECG/spO2 waveforms at 150 MHz. TrustZone supports HIPAA-aligned device security for stored data and wireless transmission, and secure boot ensures only validated clinical firmware runs. The 512 KB flash retains calibration tables and logging buffers, and low-power modes extend battery life in ambulatory designs. Its 3.3 V single-supply operation and small 10x10 mm 64-pin HTQFP footprint fit compact handheld enclosures without forced-air cooling.

🏭

Building Automation and Access Control

Access-control panels, door controllers, and HVAC zone controllers leverage the LPC55S28's security features and peripheral mix. Secure boot and TrustZone protect credential databases and prevent unauthorized firmware substitution on networked controllers, an increasing regulatory requirement. Flexcomm UARTs interface to RS-485 reader buses, SPI to memory and displays, and timers to door-relay and siren outputs; dual ADCs monitor tamper loops and power quality. The 150 MHz core runs card-decrypt and match algorithms with low latency for fast user throughput, while 512 KB flash holds extensive user tables. As a drop-in family, designers can scale to LPC55S26 in cost-optimized SKUs on the same PCB.

What is the LPC55S28JBD64K?
The LPC55S28JBD64K is a 32-bit microcontroller from NXP Semiconductors based on the Arm Cortex-M33 core running at up to 150 MHz. It integrates 512 KB of flash memory, 104 KB of SRAM, and TrustZone security, packaged in a 64-pin HTQFP (10x10 mm) exposed-pad package. According to NXP's product page, it belongs to the LPC55S2x family within the LPC5500 series and the EdgeVerse edge computing platform.
What is the maximum clock frequency of the LPC55S28JBD64K?
The LPC55S28JBD64K operates at a maximum core frequency of 150 MHz, per the DigiKey product listing. The Cortex-M33 core includes DSP instruction extensions and an Armv8-M mainline architecture with TrustZone, giving it strong real-time and signal-processing capability. At this clock rate it is well suited to motor control, digital power, and secure IoT applications that demand fast interrupt latency and deterministic execution.
How much flash and SRAM does the LPC55S28JBD64K have?
The LPC55S28JBD64K provides 512 KB of on-chip flash (512K x 8) and 104 KB of SRAM, according to the DigiKey product specification. The flash is split into banks supporting in-application programming and firmware updates. The 'K' suffix in the part number denotes the 64-pin HTQFP (10x10 mm) package. This memory combination accommodates complex RTOS-based firmware, secure boot images, and connectivity stacks such as USB and multiple serial protocols.
What is the difference between LPC55S28JBD64K and LPC5528JBD64K?
The LPC55S28 adds a security envelope over the LPC5528: the 'S' variant includes TrustZone-based secure boot and enhanced cryptographic capabilities, while the LPC5528 omits these security features. Both share the same Cortex-M33 core at 150 MHz, 512 KB flash, 104 KB SRAM, and identical 64-pin HTQFP (10x10 mm) packaging, so they are pin- and footprint-compatible. According to NXP, the whole LPC552x/S2x family is pin-, software-, and peripheral-compatible, making migration a firmware-level decision.
What is the difference between LPC55S28JBD64K and LPC55S26JBD64K?
The main difference is flash density: the LPC55S28JBD64K has 512 KB of flash while the LPC55S26JBD64K has 256 KB, per the LPC55 replacement guide by htelec. Both use the same Cortex-M33 core at 150 MHz, the same security features, and the same 64-pin HTQFP package, so they are drop-in footprint-compatible. Choose the S28 when your firmware image, RTOS, and OTA update banks exceed 256 KB; otherwise the S26 offers cost savings.
Can LPC5528JBD64K replace LPC55S28JBD64K?
Yes, as a pin-compatible footprint replacement, the LPC5528JBD64K can physically replace the LPC55S28JBD64K, since both use the identical 64-pin HTQFP (10x10 mm) package with matching core, clock, and memory specifications (150 MHz, 512 KB flash, 104 KB SRAM). However, the LPC5528 lacks the TrustZone-based secure boot and cryptographic security of the 'S' variant. If your product relies on secure boot, key storage, or the S-series security API, the replacement is not functionally equivalent and firmware must be revalidated.
What is the best drop-in replacement for LPC55S28JBD64K?
The best drop-in replacement depends on the missing capability: LPC55S26JBD64K (same security, 256 KB flash) if your image fits in half the flash; LPC5528JBD64K if security is not required; or LPC55S16JBD64K for lower memory needs. According to the htelec LPC55 MCU replacement guide, these family members are pin-, software-, and peripheral-compatible within the same 64-pin HTQFP package, enabling PCB reuse and minimal firmware changes during shortage or cost-reduction initiatives.
Where can I download the LPC55S28JBD64K datasheet PDF?
The official LPC55S28JBD64K datasheet and user manual are available from NXP's product page at nxp.com/part/LPC55S28JBD64, which hosts the LPC55S2x/LPC552x data sheet covering the full family. Distributors such as DigiKey and Mouser also link the manufacturer datasheet from their product detail pages. Avoid third-party mirror sites for security-sensitive MCU documentation, and always verify you have the latest revision from NXP directly before taping out a design.
Where can I buy LPC55S28JBD64K and what does it cost?
The LPC55S28JBD64K is stocked by major distributors including DigiKey, Mouser, Arrow, and Ampheo, and is listed on Octopart across 7 distributors. As of 2026-10-12, XAIPART lists unit pricing starting at approximately 5.20 USD at qty 1, with volume breaks down to about 3.60 USD at qty 1000; treat these as indicative and confirm live stock on the distributor pages. Note that some distributor listings have reported long lead times (up to 52 weeks has been cited by resellers), so plan procurement accordingly.
Is the LPC55S28JBD64K in stock and what is the lead time?
DigiKey's listing states "buy now, ships today," indicating stock availability at major distributors as of the latest web verification. However, one reseller (Partskeys) reports a manufacturer lead time of 52 weeks, which reflects industry-wide MCU supply conditions during allocation periods. For production planning, place a buffer order with a franchised distributor (DigiKey, Mouser, Arrow) and check real-time stock on Octopart, which aggregates availability from 7 distributors before committing a build schedule.
What is the NXP equivalent for LPC55S28JBD64K from another manufacturer?
There is no true pin-to-pin cross-brand equivalent for the LPC55S28JBD64K; cross-brand Cortex-M33 MCUs such as STM32H5 or SAM L11 from STMicroelectronics and Microchip offer similar security features but different pinouts and toolchains. According to the MCU Alternative Guide by htelec, migration to a different vendor requires PCB redesign, firmware porting, and requalification. Within NXP, the pin-compatible LPC55S26JBD64K or LPC5528JBD64K are the safest substitutes because the entire LPC552x/S2x family shares the same footprint.
What are the key specifications of the LPC55S28JBD64K engineers should know?
The LPC55S28JBD64K is an NXP microcontroller with an Arm Cortex-M33 core at 150 MHz, 512 KB flash, 104 KB SRAM, 3.3 V supply, and TrustZone security with secure boot in a 64-pin HTQFP 10x10 mm exposed-pad package. It offers Flexcomm serial interfaces (UART/SPI/I2C/I2S), a full-speed USB device controller, dual 12-bit ADCs, and DMA, fabricated on a 40-nm NVM process within the LPC5500 EdgeVerse platform, per NXP's official product information.
Is the LPC55S28JBD64K suitable for motor control applications?
Yes, the LPC55S28JBD64K is well suited to motor control thanks to its 150 MHz Cortex-M33 core with DSP instructions, hardware timers with PWM capability, and dual 12-bit ADCs that can sample phase currents. The deterministic interrupt latency of the Armv8-M core supports field-oriented control loops running at tens of kilohertz. With Flexcomm peripherals for gate-driver communication and ample flash for sensorless algorithms, it covers BLDC, PMSM, and stepper control in industrial drives and consumer appliances.
Does the LPC55S28JBD64K support TrustZone and secure boot?
Yes. As an 'S' variant of the LPC552x family, the LPC55S28 implements Arm TrustZone hardware isolation and ships with NXP's secure boot capability, per NXP's LPC552x/S2x family documentation. The Cortex-M33 mainline architecture partitions secure and non-secure execution worlds, while the on-chip flash banks can hold signed immutable boot code. This makes the part appropriate for connected products requiring root-of-trust provisioning, encrypted firmware updates, and protection of cryptographic assets at the edge.
What package does the LPC55S28JBD64K use and is there a 100-pin version?
The LPC55S28JBD64K comes in a 64-pin HTQFP (10x10 mm) package with an exposed thermal pad, and the 'K' suffix denotes this packaging. Yes - the same LPC55S28 die is also available as LPC55S28JBD100K in a 100-pin HLQFP package, as documented in the Xecor comparison of the two parts. The 100-pin version provides more GPIO and peripheral pins, but the two are not footprint-compatible, so package selection must be fixed before PCB layout.
What tools and SDK are used to develop for the LPC55S28JBD64K?
Development uses NXP's MCUXpresso IDE and MCUXpresso SDK, which include drivers, RTOS ports, and examples for the LPC55S2x family. Debugging works over SWD through the MCU-Link or LPC-Link2 probes. Because the LPC552x/S2x family is software-compatible per NXP, code written for LPC55S16 or LPC55S26 ports directly to the LPC55S28, and the secure boot image tooling (including NXP's secure provisioning tools) supports key provisioning for the S-series security features during production.

Справочные инженерные данные для LPC55S28JBD64K — сравнение, рекомендации по проектированию и информация о соответствии.

Руководство по выбору

Choose the LPC55S28JBD64K when your design needs the maximum memory of the 64-pin LPC552x/S2x family plus TrustZone secure boot - typical for connected industrial nodes, access control, and any product planning OTA firmware updates. Choose LPC55S26JBD64K (same package, 256 KB flash) when the image fits in half the memory and BOM cost matters. Choose LPC5528JBD64K when you need full 512 KB flash but no security features, saving the S-variant premium. Choose LPC55S16JBD64K or LPC55S06JBD64K for cost-reduced derivative SKUs on the identical PCB footprint. All five are pin-, software- and peripheral-compatible per NXP, so the selection is primarily a memory/security/cost decision. Note there is no cross-brand pin-to-pin equivalent - moving to STM32 or similar requires a full PCB and firmware redesign, so during shortages stay within the LPC55 family first.

Заметки по проектированию

The exposed pad on the 64-HTQFP must be soldered to a ground plane array of thermal vias - it is both the primary ground return and the thermal relief path for the 40-nm die. Use 4x4 or larger via farms under the pad with at least 0.3 mm drill holes filled or tented per your assembly process. Keep the SWDIO/SWCLK (PIO0_13/PIO0_14) traces under 10 cm and place a 100-ohm series resistor on SWDIO for hot-probe robustness during production programming.

Decouple each VDD pin with 100 nF X7R capacitors placed within 2 mm of the pin, plus a single 4.7-10 uF bulk capacitor near the supply entry. The analog domain (VDDA/VREFP) should be fed from a filtered or separate LDO rail - sharing digital supply ripple directly degrades the dual 12-bit ADC effective number of bits. Estimated: a 10 kHz-100 MHz ferrite bead with 1 uF + 100 nF on VDDA typically improves ADC noise by 1-2 ENOB relative to a shared rail.

The RESET pin is open-drain with internal pull-up; do not drive it push-pull from a supervisor IC - use an open-drain reset supervisor. For secure products, provision the S-variant key storage before final assembly because the secure boot fuses are one-time programmable and cannot be reworked. When migrating firmware from smaller-flash family members (LPC55S26/LPC55S16), verify linker regions and the flash bank layout, as image placement differs across densities.

USB0_DP/USB0_DM must be routed as a 90-ohm differential pair with length matching within 0.5 mm and no stubs; place the common-mode choke and ESD array within 5 mm of the connector. XTALIN/XTALOUT traces should be kept short (under 5 mm), guarded by ground, and away from switching signals to preserve oscillator startup margin and jitter performance for USB and CAN timing.
