• Description: Renesas 32-Bit RISC Microcomputer
• Manufacturer: RENESAS [Renesas Technology Corp]

This LSI incorporates a Bluetooth interface (BT) as hardware for the baseband processing for the
Bluetooth. This Bluetooth interface conforms to version 1.1 of the Bluetooth Specification, is
configured by combination of hardware and firmware, and provides a lower protocol stack
function to the host controller interface (HCI) layer. With this function, Bluetooth logo
certification is acquired for a baseband layer (BB) and link management protocol layer (LMP).
To configure the upper protocol stack, HCI commands which are defined by version 1.1 of the
Bluetooth Specification and 53 types of test command interface (TCI) commands are supported.
For communication between upper and lower protocol stacks, nine types of functions are prepared
as an application interface (API).
21.1
• Conforms to version 1.1 of the Bluetooth Specification
• Frequency hopping within 79 channels as a form of spread-spectrum modulation
• Supports ACL (Asynchronous Connection-Less) and SCO (Synchronous Connection-
• Controls the ACL and SCO from upper layer above HCI
• Supports all types of packets: i.e., control packets for establishing links and connections, and
• Supports point-to-point and point-to-multipoint connections (piconet)
• Mutual conversion in Voice Codec between A-law and µ-law, CVSD and linear PCM, linear
• Encryption/decryption
• Controls three power-down modes: the Hold, Sniff and Park modes
• Supports a direct interface with the Renesas RF ICs, such as the HD157100NP and
• Supports a direct interface with the STLC7550 (ST Microelectronics) or MC145483
• Includes a frequency conversion function that allows the use of a 32.768-kHz crystal resonator
• Supports unique TCI commands (53 types) and API functions (9 types) in addition to the HCI
