STA2416 Datasheet, PDF (1/38 Pages) STMicroelectronics – Bluetooth™ Baseband with integrated flash

STA2416
Bluetooth™ Baseband with integrated flash
Target Specification
Features
■ Bluetooth™ specification compliance: V1.1
and V1.2
■ SW compatible with STLC2416
■ 2 layer class 4 PCB compatible
– Point-to-point, point-to-multi-point (up to 7
slaves) and scatternet capability
■ Asynchronous connection oriented (ACL)
logical transport link
■ Synchronous connection oriented (SCO) links:
2 simultaneous SCO channels
■ Supports pitch-period error concealment
(PPEC)
– Improves speech quality in the vicinity of
interference
– Improves coexistence with WLAN
– Works at receiver, no Bluetooth implication
■ Adaptive frequency hopping (AFH): hopping
kernel, channel assessment as master and as
slave
■ Faster connection: interlaced scan for page
and inquiry scan, first FHS without random
backoff, RSSI used to limit range
■ Extended SCO (eSCO) links
■ Standard BlueRF bus interface
■ QoS flush
■ Clock support
– System clock input: any integer value from
12 to 33 MHz
– LPO clock input at 3.2 and 32 kHz or via
the embedded 32 kHz crystal oscillator cell
■ ARM7TDMI 32-bit CPU
■ Memory
– Integrated 4 Mbit flash
LFBGA120 (10x10x1.4mm)
– 64 KByte on-chip RAM
– 4 KByte on-chip boot ROM
■ Low power architecture with sleep mode
■ HW support for packet types
– ACL: DM1, 3, 5 and DH1, 3, 5
– SCO: HV1, 3 and DV
– eSCO: EV3, 5
■ Communication interfaces
– Synchronous serial interface, supporting up
to 32-bit data
– Two enhanced 16550 UARTs with 128-byte
FIFO depth
– 12 Mbps USB interface
– Fast master I²C bus interface
– Multi slot PCM interface
– 15 programmable GPIOs
– 2 external interrupts and various interrupt
possibilities through other interfaces
■ 32 KHz clock out
■ Efficient support for WLAN coexistence
■ Ciphering support for up to 128-bit key
■ Receiver signal strength indication (RSSI)
support for power-controlled links
■ Separate control for external power amplifier
(PA) for class1 power support
■ Software support: low level (up to HCI) stack or
embedded stack with profiles
– Support of UART and USB HCI transport
layers
