NXP Semiconductors S32R27 Manuals

1 Introduction The S32R is a 32-bit heterogeneous multi-core microcontroller family primarily intended for use in computationally intensive automotive RADAR applications. The device family incorporates Power Architecture® cores arranged as two independent e200z7260 for general computation and the S32R274 device also features an e200z420 core with an e200z419 checker core running in delayed lockstep configuration for safety-critical and housekeeping tasks. The family integrates high-performance signal processing features designed to support sophisticated automotive RADAR applications, and the S32R274 also integrates high accuracy analog features to further enhance it's ability to interface with a wide range of RADAR RF devices. This application note illustrates the S32R family power supply options and details the external circuitry required for power supplies, oscillator connections, and supply decoupling pins. It also discusses configuration options for clock, reset, ADC modules and the RADAR analog front-end, as well as recommended debug and peripheral communication connections (including MIPI-CSI2) and other major external hardware required for the device. The S32R family requires multiple external power supplies to operate. The main cores internal logic requires a 1.25 V power supply. This can be supplied from an external source or on some devices this can alternatively be provided by an internal DC-DC regulator that requires a dedicated supply. 3.3 V is NXP Semiconductors Document Number: AN5251 Application Note Rev. 1, 04/2018 S32R27/37 Hardware Design Guide by: NXP Semiconductors Contents 1 Introduction.............................. .............................. 1 2 S32R family package options overview..................................................................2 3 Power supply...........................................................3 4 Clock configuration...............................................15 5 Device reset configuration............... .....................17 6 Recommended debug connectors and connector pin-out definitions................................18 7 ADC overview...................................................... 22 8 RADAR analog front end..................................... 23 9 Example communication peripheral connections.......................................... ................. 29 10 High speed layout considerations..........................48 A Revision History................................................... 49
