FAQ

What is the maximum operating frequency of the LPC55S06JHI48QL?

The LPC55S06JHI48QL features an ARM Cortex-M33 core rated for operation up to 96 MHz. This frequency is achievable using the internal 96 MHz Free Running Oscillator (FRO), PLL0, or PLL1 clock sources. The FRO is factory-trimmed to ±1% accuracy across 0 °C to 85 °C and ±2% across −40 °C to 105 °C, ensuring reliable timing stability in industrial environments without requiring external crystals for basic operation. The LPC55S06JHI48QL maintains full peripheral functionality at this maximum rate.

Does the LPC55S06JHI48QL support secure boot with public-key cryptography?

Yes, the LPC55S06JHI48QL supports secure boot using RSASSA-PKCS1-v1_5 signatures of SHA256 digests, validated against RSA-2048 or RSA-4096 public keys stored in protected flash. It implements a four-key Root of Trust (RoT) scheme with revocation capability and anti-rollback protection via image key serial number tracking. The LPC55S06JHI48QL also complies with the Trusted Computing Group's DICE Specification v2.0 Level 00 for device identity composition, enabling cryptographically verifiable device attestation.

How many ADC channels does the LPC55S06JHI48QL provide, and what is its sampling capability?

The LPC55S06JHI48QL integrates a 16-bit successive-approximation ADC with 7 input channels in HVQFN48 package configuration. It achieves up to 2.0 million samples per second (Msamples/sec) with simultaneous conversion capability on differential channel pairs. The ADC supports multiple trigger sources including timers and external events, and connects directly to the integrated temperature sensor and analog comparator. Its design enables high-fidelity signal acquisition for sensor fusion and closed-loop control in applications like motor drives and medical instrumentation - all within the LPC55S06JHI48QL's thermal envelope.

What security accelerators are integrated into the LPC55S06JHI48QL?

The LPC55S06JHI48QL integrates three dedicated hardware security blocks: CASPER for elliptic curve cryptography acceleration (ECC), PRINCE for real-time AES-256 encryption/decryption of on-chip flash, and a full-featured HASH-AES engine supporting SHA-224/256 and AES-128/192/256. It also includes a Physical Unclonable Function (PUF) for silicon fingerprinting and key derivation, a True Random Number Generator (TRNG), and secure boot ROM with debug authentication. These accelerators operate independently of the CPU core, enabling the LPC55S06JHI48QL to sustain cryptographic throughput without compromising real-time task scheduling.

Is the LPC55S06JHI48QL pin-compatible with other members of the LPC55S0x family in HVQFN48?

Yes, the LPC55S06JHI48QL is pin-compatible with other HVQFN48 variants in the LPC55S0x family, including LPC55S04JHI48 and LPC55S16JHI48. All share identical pin numbering, electrical characteristics, and mechanical footprint (7 mm × 7 mm × 0.85 mm). Functional differences - such as flash size (256 KB vs. 128 KB), SRAM allocation, or peripheral enablement (e.g., second CAN FD in LPC55S16) - are implemented internally and do not affect PCB layout. This allows direct substitution during design-in or production ramp, provided firmware and power delivery meet the target variant's specifications.
