Communication interfaces (2 of 2)

Feature

Functional description

Serial peripheral interface (SPI)

● 4 channels

● SPI transfer facility

Using the MOSI (master out slave in), MISO (master in slave out), SSL (slave select), and

RSPCK (SPI clock) signals enables serial transfer through SPI operation (four lines) or

clock-synchronous operation (three lines) capable of handling serial transfer as a master or

slave

● Data formats

– Switching between MSB first and LSB first

– Transfer bit length selectable to 4 - 32 bits

– 32 bits × 4-stage FIFO transmit and receive buffers

– Up to four frames can be transmitted or received in a single transfer operation (with

each frame having up to 32 bits)

● RSPCK can be stopped automatically with the reception buffer full for master reception

Expanded serial peripheral interface

(xSPI)

● 2 channels

● Comply with JESD251

● Multiple slave up to 2 slaves

● Protocol mode: 1/4/8pin with SDR/DDR

1S-1S-1S, 4S-4D-4D, 8D-8D-8D

● Support OctaFlash, OctaRAM, HyperFlash and HyperRAM

● Protocol mode: 2/4pin with SDR compatible with QSPI

1S-2S-2S, 2S-2S-2S

1S-4S-4S, 4S-4S-4S

● Configurable address length

● Configurable initial access latency cycle

● Support XiP mode

● Support up to 256 MB address space

● Prefetch function for burst-read with low latency

● Outstanding buffer for burst-write with high throughput

● Manual command configurable up to 4 commands

● Output clock/input strobe port timing shift

● Automatic command after released reset: up to 4 commands

● 1.8 V/3.3 V selectable for xSPI0 and 3.3 V fix for xSPI1

Analog

Feature

Functional description

12-bit A/D converter (ADC12)

● 12 bits × 2 units (unit 0: 4 channels, unit 1: 4 channels)

● 12-bit resolution

● Conversion time

0.84 µs per channel

● Operating mode

Scan mode (single scan mode, continuous scan mode, or 3 group scan mode)

Group priority control

● Sample-and-hold function

Common sample-and-hold circuit included

In addition, channel-dedicated sample-and-hold function (3 channels: in both unit 0 and unit

1) included

● Sampling variable

Sampling time can be set up for each channel

● Double trigger mode (A/D conversion data duplicated)

● Three ways to start A/D conversion

Software trigger, timer (MTU3, ELC) trigger, external trigger

● Event linking by the ELC

Temperature sensor unit (TSU)

● 1 channel

● Relative precision: ±1°C (typ)
