有人关注MicroChi的SAMA5D2系列吗?内嵌DDR2,128Mbit ~1Gbit 都有。参考设计以及驱动等资料非常完善

Summary
The SAMA5D225C-D1M System in Package (SiP) integrates the ARM® Cortex®-A5 processor-based SAMA5D22C MPU with 128 Mbit (16 Mbytes) of DDR2-SDRAM in a single package.  By combining the high-performance, ultra-low-power SAMA5D2 with DDR2-SDRAM in a single package, PCB routing complexity, area and number of layers is reduced in the majority of cases.  This makes board design easier and more robust by facilitating design for EMI, ESD and signal integrity.  This SiP targets applications using an Linux, RTOS or bare metal for development and is available in a BGA196 package.

Additional Features
ARM Cortex-A5 core:
Up to 500 MHz, ARMv7-A architecture, ARM TrustZone, NEON™ Media Processing Engine, 8 Kbyte Embedded Trace Buffer (ETB)
Memory Architecture
Memory Management Unit
32-Kbyte L1 data cache, 32-Kbyte L1 instruction cache
128-Kbyte L2 cache configurable to be used as an internal SRAM
128 Mbit DDR2-SDRAM
One 128-Kbyte scrambled internal SRAM
One 160-Kbyte internal ROM, 64-Kbyte scrambled and maskable ROM embedding boot loader/Secure boot loader, 96-Kbyte unscrambled, unmaskable ROM for NAND Flash BCH ECC table
High-bandwidth scramblable 16-bit Double Data Rate (DDR) multiport dynamic RAM controller supporting the internal DDR2-SDRAM, including the “on-the-fly” encryption/decryption path
8-bit SLC/MLC NAND controller, with up to 32-bit Error Correcting Code (PMECC)
Low-Power Modes
Ultra Low-power mode with fast wakeup capability
Low-power Backup mode with 5-Kbyte SRAM and Sleep Walking™ features, Wakeup from up to nine wakeup pins, UART reception, analog comparison, Fast wakeup capability, Extended Backup mode with DDR2-SDRAM in Self-Refresh mode
Peripherals
LCD TFT controller up to 1024x768, with four overlays, rotation, post-processing and alpha blending, 24-bit parallel RGB
ITU-R BT. 601/656/1120 Image Sensor Controller (ISC) supporting up to 5 M-pixel sensors with a parallel 12-bit interface for Raw Bayer, YCbCr, Monochrome and JPEG-compressed sensor interface
Two Synchronous Serial Controllers (SSC), two Inter-IC Sound Controllers (I2SC), and one Stereo Class D amplifier
One Peripheral Touch Controller (PTC) with up to 4 X-lines and 8 Y-lines (32-channel capacitive touch)
One Pulse Density Modulation Interface Controller (PDMIC)
One USB high-speed device port (UDPHS) and one USB high-speed host port or two USB high-speed host ports (UHPHS), plus one High-Speed Inter-Chip (HSIC) host port.
One 10/100 Ethernet MAC (GMAC)
Energy efficiency support (IEEE 802.3az standard), Ethernet AVB support with IEEE802.1AS time stamping, IEEE802.1Qav credit-based traffic-shaping hardware support, IEEE1588 Precision Time Protocol (PTP)
Two high-speed memory card hosts:
SDMMC0: SD 3.0, eMMC 4.51, 8 bits
SDMMC1: SD 2.0, eMMC 4.41, 4 bits only
Many other serial, timer and A/D modules
Up to 90 I/Os
Safety and Security:
Integrity Check Monitor based on SHA256, Crypto engine (SHA512, AES256, TDES), TRNG, tamper pins, Secure Boot Loader, Programmable fuse box, On-the-fly AES   encryption/decryption on DDR2-SDRAM and QSPI, 5 Kbytes of internal scrambled SRAM, 256 bits of scrambled and erasable registers, Independent watchdog, Main crystal clock failure detector

手册写的很完善,远超nuvoton、全志了。

就是,图形 图像加速相关的模块没有

我看好像有多层alpha blending等叠加功能

价格差5倍,差评

10美金还好吧
你是和f1c100比差5倍吗?microchip的芯片是工业级的,而且资料丰富不具有可比性

10刀的话还可以,偏贵了。不过atmel你是知道的,随随便便就缺货了能搞死你。

microchip官网我试了,可以随便下单,一周内从上海发货,感觉很好买呀

Mitko 说:

ATSAMA5D21更便宜,可能制造廉价的电路板。我对Allwinner H2/H3更感兴趣,有一些不太昂贵的电路板,如Orange Pi Zero,但没有很多I/O和集成ADC。

ATSAMA5D21不带DDR,自己做板要难一点
