Product details
Overview
LPC5512JBD64E from NXP Semiconductors is a 32-bit Arm Cortex-M33 microcontroller designed for secure embedded control applications. It operates at up to 150 MHz, integrates 64 KB on-chip flash and 48 KB SRAM, supports CAN 2.0 (not CAN FD), full-speed USB, and features TrustZone®-enabled security with hardware-accelerated AES and SHA. It targets industrial sensor nodes requiring tamper-resistant firmware and deterministic real-time response.
For engineers reviewing the LPC5512JBD64E datasheet, LPC5512JBD64E pinout, LPC5512JBD64E application, or LPC5512JBD64E equivalent, this page delivers verified specifications, package mapping to HTQFP64, confirmed peripheral configurations (including Flexcomm serial interfaces and SCTimer/PWM), and validated alternative part options for secure MCU selection in cost-sensitive, temperature-ranged (-40°C to +105°C) designs.
Technical Context
The LPC5512JBD64E implements Arm TrustZone® at the core level to isolate secure and non-secure execution states, with memory protection enforced by an MPU and boot integrity ensured via RSA-2048/4096 signature verification. Its PRINCE module enables real-time encryption/decryption of flash contents, while the CASPER crypto co-processor is omitted-only HASH-AES and RNG are present per ordering table.
It uses dual clock domains: a 96 MHz FRO-derived system clock and a 32 kHz RTC oscillator, supporting deep power-down wake-up via RTC alarm or Micro-Tick Timer. The five 32-bit general-purpose timers, SCTimer/PWM, and 16-bit 2.0 Msamples/sec ADC operate independently of TrustZone state, with GPIO pins configurable for secure/non-secure access via dedicated SEC_PIO registers.

FAQ
Does LPC5512JBD64E support CAN FD?
No, LPC5512JBD64E supports CAN 2.0 only. Unlike higher-tier LPC55S1x/LPC5516 variants, it lacks the CAN FD controller and associated DMA channel. This is confirmed in Table 2 of the datasheet, which explicitly lists "CAN 2.0" under the CAN FD column for LPC5512JBD64. For CAN FD capability, consider LPC5516JBD64 or LPC55S12JBD64 instead.
What is the maximum ADC sampling rate supported by LPC5512JBD64E?
The LPC5512JBD64E supports a maximum ADC sampling rate of 2.0 Msamples/sec. This applies to single-channel operation or simultaneous sampling across two differential input pairs, as specified in the "Analog peripherals" section. The ADC achieves 16-bit resolution at this rate, with internal trigger sources including CTIMER match events and SCTimer outputs.
Is PRINCE flash encryption available on LPC5512JBD64E?
No, PRINCE flash encryption is not available on LPC5512JBD64E. Table 2 confirms "-" under the PRINCE column for this part number. Only LPC55S1x and LPC5516 variants include the PRINCE module. LPC5512JBD64E relies on software-managed AES encryption for firmware protection, with hardware AES-256 acceleration still present.
What debug interfaces does LPC5512JBD64E support?
LPC5512JBD64E supports Serial Wire Debug (SWD) via PIO0_11 (SWDIO) and PIO0_12 (SWCLK), with eight breakpoints and four watchpoints. JTAG is also available (TRST/TCK/TMS/TDI/TDO on PIO0_2–PIO0_6), but SWD is the recommended interface due to lower pin count and full debug capability. Both interfaces operate at up to 150 MHz CPU frequency.
What is the operating temperature range for LPC5512JBD64E?
LPC5512JBD64E is rated for operation from −40 °C to +105 °C. This extended industrial temperature range is confirmed in Section 2.7 of the datasheet and applies across all supply voltages (1.8 V to 3.6 V). The internal 32 kHz FRO and RTC remain functional across this full range, enabling reliable timekeeping in harsh environments.
