NXP Semiconductors LPC5502JBD64E

Overview

LPC5502JBD64E from NXP Semiconductors is a 32-bit ARM Cortex-M33 microcontroller designed for secure, low-power embedded control applications. It operates at up to 96 MHz, integrates 64 KB flash and 48 KB SRAM, includes CAN 2.0 interface, 45 GPIOs, and a 16-bit 2.0 Msamples/sec ADC with nine input channels - deployed in industrial sensor nodes requiring deterministic real-time response and firmware integrity.

For engineers reviewing the LPC5502JBD64E datasheet, LPC5502JBD64E pinout, LPC5502JBD64E application, or LPC5502JBD64E equivalent, key selection criteria include its HTQFP64 package compatibility, TrustZone®-enabled security architecture without CASPER/PRINCE, CAN 2.0 (not CAN FD), and absence of PUF/Secure Boot support compared to LPC55S0x variants.

Technical Context

The LPC5502JBD64E implements ARMv8-M architecture with TrustZone® for hardware-enforced memory isolation, but omits CASPER crypto co-processor and PRINCE flash encryption-confirmed by ordering table data. Its clock system combines internal FRO (96 MHz ±1% over 0–85°C) and dual crystal oscillators (32.768 kHz RTC + 16–32 MHz main), supporting PLL-based CPU scaling without external high-frequency sources.

Digital peripherals include two DMA controllers (23+10 channels), five 32-bit general-purpose timers, SCTimer/PWM with 16 match/capture registers, PLU for state-machine logic, and eight Flexcomm interfaces configurable as UART/I²C/SPI/I²S-each with FIFO and fractional baud-rate generation. Analog subsystem comprises one 16-bit ADC (2.0 Msamples/sec, simultaneous dual-channel conversion), comparator, and integrated temperature sensor.

FAQ

What is the maximum operating frequency of the LPC5502JBD64E?

The LPC5502JBD64E operates at a maximum CPU frequency of 96 MHz, achieved using the internal Free Running Oscillator (FRO) or PLL-synthesized clocks derived from internal or external sources. This frequency is validated across the full −40 °C to +105 °C temperature range and 1.8–3.6 V supply, enabling deterministic real-time performance in industrial control loops without external crystal dependency.

Does the LPC5502JBD64E support CAN FD or only classical CAN?

The LPC5502JBD64E supports only CAN 2.0, not CAN FD. This is explicitly confirmed in Table 2 of the datasheet, which lists "CAN2.0" under the CAN FD column for all LPC550x variants including LPC5502JBD64E. Designers requiring CAN FD must select an LPC55S0x variant such as LPC55S06JBD64.

What security features are included in the LPC5502JBD64E?

The LPC5502JBD64E includes ARM TrustZone® for hardware-enforced memory isolation between secure and non-secure worlds, but excludes CASPER crypto co-processor, PRINCE flash encryption, PUF, Secure Boot, and HASH-AES modules - all marked as "-" in Table 2. Its security model relies solely on TrustZone® partitioning without cryptographic acceleration or root-of-trust capabilities.

How many ADC channels does the LPC5502JBD64E support?

The LPC5502JBD64E supports nine ADC input channels, as specified in Table 2 under "ADC Channels" for the LPC5502JBD64 variant. These are implemented in a single 16-bit ADC subsystem capable of simultaneous conversions on differential channel pairs, with inputs mapped to specific GPIO pins (e.g., PIO0_10/ADC0_1, PIO0_11/ADC0_9) per the pin description table.

What is the package type and thermal pad requirement for LPC5502JBD64E?

The LPC5502JBD64E uses the HTQFP64 package (SOT 855-5), a 10 × 10 × 0.5 mm plastic low-profile quad flat package with 64 leads and 0.5 mm pitch. Its exposed thermal pad must be connected to VSS (ground) for thermal dissipation and electrical stability - a requirement explicitly noted in the pin configuration diagram and critical for sustained operation at 96 MHz in industrial ambient temperatures.
