ML696201 and ML69Q6203
Preliminary
• NAND Flash memory controller
- SmartMedia Standard 2000 compliant (512-Bytes/sector)
- Supporting SmartMedia of 8 MB to 128 MB
- Built-in ECC circuit
- 512-Byte/2048-Byte auto write/read function
- Switchable to the IDE controller using the IDEMODE pin
• RTC
- 1-second clock generation function from 32.768 kHz
- Built-in 32-bit 1-second clock counter
- 32-bit compare interrupt function
• GPIO
- Built-in GPIO of 16 pin x 5 channels (GPIOA, GPIOB, GPIOC, GPIOD,
GPIOE) and 7 pin x 1 channel (GPIOF)
- Input/output can be set in units of bits
- GPIOA[15:00], GPIOB[15:00] and GPIOC[15:00] can be set to an exter-
nal bus by setting the EXTBUS pin
- GPIOD[15:00] can be used to select a secondary function in units of bits.
- GPIOE[15:12] can be used as external interrupts.
- Only GPIOE[15] is 5-V tolerant input
- GPIOF[6:0] function as IDE data, when the IDE controller mode is set
using the IDEMODE pin.
• I
2
S transmission/reception
- Sampling frequencies of 32, 44.1, and 48 kHz, as well as 1/2 and 1/4 of
these frequencies are supported
- System clock is 256 times the sampling rate
- Channel data length is 16 bits
- Data buffer is 9,216 bytes (shared by transmission and reception)
- With or without 1-bit delay, left/right reversible
• Clocks
- Can connect a 48-MHz crystal oscillator and input an external clock
directly.
- The RTC section can connect a 32.768-kHz crystal oscillator.
- Can connect an 11.2896-MHz crystal oscillator for audio and input an
external clock directly.
• Power Management
- Power down mode – The power supply can be disabled to all sections,
except for the Real-time Clock section.
- Stop mode – Software disables clock supply to the main section including
the processor
- Halt mode – Partially disables clock supply
- Clock gear – Software can dynamically change clock to 1/1, 1/2, 1/4,
1/8, 1/16 or 1/32 of the clock input frequency
- Clock control – Software can stop clock supply for each function
• Package
- 272-pin LFBGA, 0.65 mm ball pitch
