32-bit Low-Power Microprocessors

Sophisticated wearable technology, wireless sensor networks and other smart appliances that need to connect to the Internet of Things (IoT) require high-performance and power-efficient devices that also incorporate security features to protect these applications. To meet these requirements, our 32-bit Arm^® Cortex^®-A5 based microprocessors (MPUs) are designed to efficiently run on Linux^® platforms and modern Graphical User Interfaces (GUIs) while conserving energy in sleep or back-up modes.

Benefits of 32-bit MPUs

Two Ultra-Low-Power Sleep Modes

ULP0 Mode with configurable sleep current /wake-up settings from 250 μA/4.7 ms to 3.2 mA/13 μs; wake up from any interrupt source
ULP1 Mode sleep current down to 300 μA with fast 15 μS, with wake up from restricted pin set
Patented SleepWalking feature enables peripherals to asynchronously wake up from sleep in ULP1 mode, for example, when triggered by activity on a communications line

High-Performance, Power-Efficient Arm Cortex-A5 Core

500/536 MHz (D2/D3) CPU with Floating Point Unit (FPU)
140 mW (233 μA)/MHz operation
Arm Neon™ technology improves DSP operations (’D2)
- –1.32V V_DD core
32 KB L1 data/instruction caches
128 KB L2 cache (’D2)
128 KB on-chip SRAM
LPDDR1/LPDDR2 support and LPDDR3L support (’D2)

Back-Up Mode Enables Battery Operation

VDDBU pin for battery domain with low 4.5 μA backup current (typ.)
Real Time Clock (RTC) with alarm and security module remain active
5 KB SRAM data and 256-bit register file save application context
Optional DDR Self-Refresh Mode maintains external SDRAM contents for faster recovery (40 μA)
Wake up from RTC alarm, 10 wake-up pins, analog comparator or LP UART RX character input

Comprehensive Peripheral Set and High-Grade Security Features

SDIO/SD/eMMC, QSPI, Hi-Speed USB, 10/100 and Gigabit Ethernet (‘D3), Flexcoms, CAN FD, 12-bit Analog to Digital Converters (ADCs), timers, 24-bit TFT LCD controller with overlays, resistive touch, capacitive touch (D2), an audio subsystem with PLL, I²S™, SSC/TDM channels, a class D amplifier and digital microphone (’D2)
Arm TrustZone^® technology, crypto engine, unique on-the-fly encryption and decryption of software code from the external DRAM and QSPI, secure boot, tamper detection pins, safe erasure of security-critical data, voltage and frequency monitoring, and a unique ID in each device provide exceptional data security (D2)
